If an object has a larger potential energy than kinetic energy,

On a frictionless tabletop, a force is applied to an object: the object’s velocity is horizontal and the force is perpendicular to the tabletop. Which of the following is true?

A box is pushed across a rough horizontal floor by a force acting parallel to the floor in the direction of motion. A force doing no work during the motion is

A physics professor places a soda pop can on the table and asks a student to identify the forces acting upon the can and the directions of each force. The two forces acting on the soda pop can are

A box is pushed eastward across a rough horizontal floor by a force acting parallel to the floor. A force providing an impulse directed westward on the body is

Two springs are hung from a ceiling and carry identical masses. The first spring has a spring constant twice as large as the second spring. The masses on each spring are pulled down from their equilibrium positions the same distance and are then released. The amplitude of the oscillation is

A car rounds a curve while maintaining constant speed. Which of the statements is correct?

A racquetball is dropped from a height of one meter. It bounces off the floor and rises to a height of 0.8 m. The collision with the floor was

A father and his young daughter are on very clean ice, so there is very little friction (the father has more mass than the daughter). The father pushes his daughter forward and she slides away at a speed of 3 m/s. The father’s velocity is

If you drop a ball in the absence of air resistance, it accelerates downward at approximately 10 m/s2. If instead you throw the ball upward, then its downward acceleration after release is approximately
