The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

The particles that are found in the nucleus of an atom are

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
