Sample AP Physics 1 practice question

A student pushes a heavy crate across a rough horizontal floor at a constant velocity of 1.5 m/s. The student claims that the net force on the crate is zero. Which statement best justifies this claim using Newton's laws?

Valid because constant velocity implies zero acceleration, so the applied force balances the kinetic friction.

Correct answer

Valid because constant velocity implies zero acceleration, so the applied force balances the static friction.

Invalid because motion requires a net force, so the applied force must be greater than the kinetic friction.

Invalid because motion requires a net force, so the applied force must be greater than the static friction.

Explanation

Connecting constant velocity to zero acceleration applies Newton's first law, confirming that the vector sum of forces (applied force and kinetic friction) must be zero.
