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

A
It would move in a line tangent to the circular path.
B
It would move in a line toward the circle’s center.
C
It would move in a line away from the circle’s center.
D
It would move in a curved, circular path.
5

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

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

A centripetal force causes circular motion because it accelerates an object

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

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

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