WorksheetsCh.5 Uniform Circular Motion
Total questions: 11
Worksheet time: 8mins
What is the name of the acceleration that occurs when an object moves in a circle?
Centripetal acceleration
Centrifugal acceleration
Linear acceleration
Tangential acceleration
What is the direction of the velocity of an object moving in a circle?
Along the path of the circle
Perpendicular to the radius of the circle (tangent)
Opposite to the centripetal force
Toward the center of the circle
What happens to the velocity of an object moving in a circle if there is no force to turn it?
It continues moving in a straight line
It slows down and stops
It changes direction and moves outward
It changes direction and moves inward
What is the force that causes an object to move in a circle called?
Centripetal force
Centrifugal force
Inertial force
Frictional force
What is the period of motion?
The time it takes for an object to complete one revolution
The distance an object travels in one second
The speed of an object moving in a circle
The force exerted on an object moving in a circle
What is the frequency of motion? (more of this in ch.7/8)
The number of revolutions an object makes in one second
The time it takes for an object to complete one revolution
The speed of an object moving in a circle
The force exerted on an object moving in a circle
How can the "speed" of an object in uniform circular motion be calculated?
Circumference divided by Period
Change in position divided by change in time
Change in velocity divided by change in time
Change in acceleration divided by change in time
What is the equation for the magnitude of centripetal acceleration?
Speed divided by radius
Radius divided by speed
Speed squared divided by radius
Radius squared divided by speed
What happens to the centripetal acceleration if the speed along the circular path increases?
It decreases
It remains the same
It increases
It becomes zero
If the variable z is measured as we change the size of the circle (diameter or circumference); Then determine the ideal responding variable (variable z) for Uniform Circular Motion.
How would you "solve for the speed" (variable z) of an object moving in UCM from this formula, where radius is represented by variable Ι :
a = lz2
