For each force there is an equal and opposite reaction. What is the relationship between mass and velocity to kinetic energy? - answer Kinetic energy is equal to 1/2 the mass multiplied the square of its velocity therefore when mass is doubled so is the net energy, however, when velocity is doubled energy is quadrupled. What is tension? - answer stretching force by pulling at opposite ends What is compression? - answer Crushing by squeezing together What is bending? - answer Loading about an axis. Bending causes compression on the side the person is bending toward and tension to the opposite side What is shearing? - answer Damage by tearing or bending by exerting force different parts in opposite directions at the same time.
