AP Physics C - Quiz 6: Work and Kinetic Energy

average power, P

work done in a time interval divided by the time interval

kinetic energy, K

energy of motion, one-half an object's mass times the square of its speed

net work, W

work done by all the forces acting on an object

power, P

rate of doing work with respect to time

work, W

done when a force acts on something that undergoes a displacement from one position to another

work done by a force

integral, from the initial position to the final position, of the dot product of the force and the
infinitesimal displacement along the path over which the force acts

work-energy theorem

net work done on a particle is equal to the change in its kinetic energy

negative

The work done against a force is the __________ of the work done by the force.

particles

The kinetic energy of a system is the sum of the kinetic energies of all the __________ in the system.

relative, positive, motion

Kinetic energy is __________ to a frame of reference, is always __________, and is sometimes given special names for different types of __________.

work-energy

Because the net force on a particle is equal to its mass times the derivative of its velocity, the integral for the net work done on the particle is equal to the change in the particle's kinetic energy. This is the __________ theorem
