Without inertia, how would an object that is experiencing a centripetal force behave?

A
It would move in a line away from the circle’s center.
B
It would move in a curved, circular path.
C
It would move in a line tangent to the circular path.
D
It would move in a line toward the circle’s center.

How do inertia and centripetal force combine to keep an object moving in circular motion?

A
Centripetal force acts toward the center of the circle, and inertia keeps the object moving forward.
B
Centripetal force acts toward the center of the circle to overcome inertia, which acts away from the center.
C
Inertia acts toward the center of the circle, and centripetal force keeps the object moving forward.
D
Inertia acts toward the center of the circle to overcome centripetal force, which acts away from the center.

An object is in circular motion. How will the object behave if the centripetal force is removed?

A
It would move in a line toward the circle’s center.
B
It would move in a line away from the circle’s center.
C
It would move in a line tangent to the circular path.
D
It would move in a curved, circular path.

A centripetal force causes circular motion because it accelerates an object

A
toward the center of a circle, which changes the direction of motion but not the speed.
B
toward the center of a circle, which changes the speed of motion but not the direction.
C
along the edge of a circle, which changes the direction of motion but not the speed.
D
along the edge of a circle, which changes the speed of motion but not the direction.
