Choose whether each of the following statements is true or false. In order to move a massive crate sitting on the floor, the force you apply to the crate has to the force overcome the force of the crate pushing back on you. An object can be moving in one direction while the net force acting on it is in another direction. An object can be in motion and still have zero net force acting on it. An object at rest has no forces acting on it.

1. False

The force you apply on crate is equal and opposite to the force that crate applies on you by Newton's third law of motion.

The force must over come the static frictional force between the crate and the floor.

2. True

The object can move along another direction than the direction of net force. For example, when a car slows down, the net force is opposite to the direction of motion.

3. True

An object moving at constant velocity has zero net force acting on it.

4. False

An object at rest has forces acting on it but the summation of all the forces is zero i. e. the net force is zero.
