Every object with mass exerts a gravitational force on every other object with mass. The gravitational force between which of the following two objects would be the easiest to detect with measuring equipment

A. a human and a dog
B. An electron and a bowling ball
C. A baseball and a bowling ball
D. Earth and the moon

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
