Question

Energy has many different forms: ____________ energy is the energy of motion, for every moving object and living thing; _______________ energy is a stored energy, ready to be used and converted into other types of energies.
Kinetic and potential energy are both ______________ proportional to the ___________ of the object under study. If you take a ____________-kg ball and place at the top of an inclined plane, at 4 m from the ground, it will have a ______________ energy of 392 J. While it slips down the plane, its ______________ energy increases, its ______________ energy decreases, and its ______________ energy remains constant. If we neglect other factors such as friction, we can assume that the ball, once arrived at the bottom of the plane, it will have a velocity of ___________ m/s.


The choices for the blanks are: 0, 10, 86, 392, directly, height, inversely, kinetic, mass, potential, total and velocity.
