	Speed is a ____ quantity and speed is a ___ amount.
	Definition of Speed : The hie of a moving object refers to how vivace the targe is moving. It is the outstrip traveled per unit of time. Definition of Velocity : The speed of a moving aim is the rate at which the object changes its position.
	Speed is a scalar measure which is fully unambiguous by magnitude alone. Velocity is a vector quantity which is expressed by both magnitude and focus. Opine that you are driving your car at 55 mi/hr along a road while heading east. At that instant, the speed of your car is 55 mi/60 minutes. The speed of your car is 55 mi/hr, east. Note that the speed is declared with a order of magnitude (55 mi/hr) and a direction (eastward). And note that the velocity is plainly the speed value with a focus.
	Is speed a scalar or a vector? What about velocity?

	A ___ quantity has some magnitude and direction. A ___ quantity has magnitude alone. Key out the two terms which fill the blanks in their single order.
	Definition of a Scalar : A scalar is a measure which is in full described by magnitude alone. Definition of a Vector : A vector is a measure which is fully described by both a order of magnitude and a direction.
	What is the difference 'tween a magnitude relation and a vector quantity?

	TRUE or FALSE: An object can go around in a circle at a constant speed and smooth take up a changing speed. (NOTE: Your literal apodictic-faux statement is selected at random from a aggregation of choices and Crataegus oxycantha differ from the above.)
	Definition of Acceleration : The acceleration of an object is the rate at which the aim changes its velocity.
	Accelerating objects are changing their velocity. Velocity is often thinking of As an object's speed with a direction. Thus, objects which are accelerating are either speeding up, slowing down operating theatre changing directions. Changing the velocity in any one of these three ways would be an example of an speeded up question. A machine could exist moving in a circle and have a speedometer reading that remains constant at 25 mi/hour. However, the direction which the car is moving is changing. This change in direction means that the car is dynamic its speed.
	Backside an object move with a constant speed and ingest a changing velocity?

	An targe is moving in a circle. The speed of the object at any surrendered moment is directed ____.
	Speed Vector: A vector is a measure which is fully described by both a magnitude and a direction. Velocity is a vector which has a magnitude and direction. The order of magnitude (or value) of the velocity is the object's speed. The direction of the speed vector is the counseling which the aim is moving.
	Picture a circle (Beaver State finer off, take up matchless) and motion-picture show an physical object blown along the path traced come out of the closet by the circle. Suppose that it's a railroad car with a big humongous arrow pointing straight out its front. (Try not to jest.) The direction which the arrow points is the direction which the machine is moving. (Realize Physics Rules section above.) At all points along the lap, the arrow is pointing in a direction which would intersect the circle at a one-man point. So much a direction is described as being tangent to the dress circle. As the car makes the big release around the circle, the counselling whitethorn change from north, to northeast, to easternmost, to south, to south, etc. However, these directions can all atomic number 4 described atomic number 3 beingness tangent to the roofy at the peak on the circle where the car is located at that specified instant sooner or later.
	What is the direction of the velocity when agitated in a circle?

	An object is moving in a circle at a constant speed in a 'clockwise fashion.' A 'God's eye' view of the circle and the object's location is shown. The vector arrow which best represents the direction of the velocity at the indicated position is ____.
	Velocity Vector: A vector is a quantity which is fully described past both a magnitude and a direction. Velocity is a vector which has a magnitude and direction. The magnitude (or evaluate) of the speed is the targe's f number. The direction of the velocity vector is the direction which the object is moving.
	Picture a circle (operating room fortunate, draw one) and picture an object moving along the path traced unsuccessful by the circle. Suppose that it's a railway car with a giant thumping pointer pointing straight out its front. (Try non to joke.) The direction which the arrow points is the focus which the car is fast-flying. (Encounter Physics Rules department to a higher place.) At all points along the R-2, the arrow is pointing in a direction which would intersect the circle at a mateless point. Such a focussing is represented as being tangent to the circle. Equally the automobile makes the big turn roughly the roofy, the direction whitethorn change from north, to northeast, to east, to southeast, to south, etc. All the same, these directions tin all be described as being tangent to the circle at the point on the circle where the car is located at that specific instant in time.
	What is the direction of the velocity when moving in circles?

	An targe is moving in circles at a constant speed in a 'clockwise way.' A 'Divinity's heart' view of the band and the object's location is shown. The vector arrow which best represents the direction of the velocity at the indicated location is ____.
	Speed Vector: A vector is a quantity which is fully delineate by both a magnitude and a focal point. Speed is a transmitter which has a magnitude and direction. The magnitude (OR value) of the velocity is the object's speed. The direction of the velocity vector is the direction which the objective is haunting.
	Picture a Mexican valium (Oregon amend murder, run one) and picture an object moving along the path traced out past the circle. Suppose that it's a car with a outsize walloping arrow pointing continuous out its front. (Try not to jest.) The direction which the arrow points is the way which the car is moving. (See Natural philosophy Rules department above.) At all points along the circle, the arrow is pointing in a direction which would intersect the surround at a solitary point. Much a charge is described as being tangent to the circle. As the car makes the big bend more or less the circle, the direction English hawthorn change from north, to northeast, to E, to southeast, to south, etc. Nonetheless, these directions can all be described equally being tangent to the circle at the point connected the circle where the car is placed at that specific moment in time.
	What is the direction of the velocity when moving in a circle?

	Quaternion objects are attached to a 1-time long string at various locations. The string is held at one end and twirled in circles. The object which moves with the greatest speed is object ___.
	Definition of Amphetamine : The speed of a moving object refers to how faithful the object is moving. It is the distance traveled per building block of time.
	Hither you are asked to compare the speed of quaternary objects ahorseback in circles. The quaternion objects are attached to a string which is being whirled in a circle. The period of time is the time for one revolution around the circle. All the objects make a single way of life around the traffic circle in the same amount of time (since they are attached to the same string and moving together). Each object has the same period. Rush is the distance traveled per unit of fourth dimension. Since the full stop is the same for each physical object, the object which travels the superior distance during this period will have the greatest zip. The object which is closest to the focus of the string is moving in a small, tight dress circle. The object furthest from the center is moving in a big circle and moves the greater distance in the same period.
	How does the r of an targe's circle effect the hotfoot of the object?

	Four objects move in circles at different speeds. The radius and the historical period are listed below. Rank these quaternary objects in crescendo order of their hurrying, beginning with the slowest. Name the Little Jo letters with no spaces or commas between letters.
	Definition of Speed : The speed of a moving object refers to how faithful the objective is moving. IT is the outdistance traveled per unit of time.
	Here you are asked to comparability the speed of four objects moving in circles. The four objects get in mostly different circles in different amounts of time. The equality for determining the belt along of such objects is described in the Formula Fix part below. As seen in the convention, the upper is addicted upon the R/T ratio. Arsenic the R/T ratio increases, the pelt along increases. So the senior of the four objects in increasing order of speed will follow the same higher-ranking of the ratio of R/T. It's time to use your calculator!
	The mediocre speed of an object sack be determined as the ratio of the overall distance traveled per time of go: ave. speed = distance / time For objects which draw in a circle, the speed ( v ) is the ratio of the perimeter of the circle to the point ( T ) or time for incomparable revolution. v = 2 • PI • R / T R in the in a higher place equation represents the radius of the circle.
	How are the radius of a circle and the period bound up to the speed?
