Which vector represents the acceleration of the ball?
A ball is moving at constant speed around the circle. Which letter represents the acceleration of the ball?
A
B
C
D
Nonsense. The ball can't be accelerating while moving at a constant speed.
Imagine a child on a merry-go-round, spinning as it turns. If the child is holding a ball, then reaches out and releases the ball off the side of the merry-go-round, in what direction will it travel?
Toward the center of the merry-go-round
Directly opposite the center of the merry-go-round
In a straight line tangential to the circular path of the merry-go-round
Around in a circular path identical to how it was traveling prior to release
In what direction does the child feel herself being pulled while on the merry-go-round?
Toward the center of the merry-go-round
Directly opposite to the center of the merry-go-round
Tangentially along the path of the circular motion
None of these
The larger the mass of an object...
The smaller the force of gravity.
The larger the force of gravity.
Mass has no effect on the amount of gravity an object experiences.
How is the gravitational force between two objects related to their mass
They are directly proportional
They are inversely proportional
They do not affect each other
They are equal
How is the gravitational force between two objects related to their distance (radius apart)
They are directly proportional
They are inversely proportional
They do not affect each other
They are equal
