Motion is changing all the time. When you stand up, begin to run, or turn a corner, your motion is changing. These changes in motion all have something in common. They all start with a push or a pull. What happens when you push or pull an object? Make a claim about how a push or pull affects the motion of a water tube.

In a system with only a single force acting upon a body, what is the relationship between the change in kinetic energy and the work done by the force? answers: work is equal to the change in kinetic energy. work depends on the square of the change in potential energy. work is equal to the negative of the change in kinetic energy. work is equal to the square of the change in kinetic energy
