Linear acceleration is to force as angular acceleration is to

• kinetic energy

• angular velocity

• rotational inertia

• torque

• angular momentum

A girl stands on a rotating merry-go-round without holding on to a rail. The force that keeps her moving in a circle is the

• frictional force on the girl directed away from the center of the merry-go-round

• frictional force on the girl directed toward the center of the merry-go-round

• normal force on the girl directed away from the center of the merry-go-round

• normal force on the girl directed toward the center of the merry-go-round

• weight of the girl
