7. Kinetic Energy and Work Kinetic Energy
www.asc.ohio-state.eduKinetic Energy: The kinetic energy of a moving object: k = 1 2 mv 2 • Kinetic energy is proportional to the square of the velocity. If the velocity of an object doubles, the kinetic energy increases by a factor of four. • Kinetic energy is proportional to the mass. If a bowling ball and a ping pong ball have the same velocity, the bowling ...

www.paulding.k12.ga.usCalculating kinetic energy If we know the mass of an object and its velocity we can determine the amount of kinetic energy. kinetic energy = 1/2 (mass of object)(velocity of object)2 or KE = 1/2 mv2 or KE = 0.5mv2 The SI unit for kinetic energy is the Joule (J). A …
POTENTIAL AND science KINETIC ENERGY
irp-cdn.multiscreensite.comIt was potential energy because the washer could swing due to its relative position and gravity. This kind of potential energy is known as gravitational potential energy. What’s interesting about a pendulum, though, is that when you let go of it, the potential energy gradually transforms into kinetic energy. And then it gets faster and faster ...

www.uek12.orgenergy. When you are walking or running your body is exhibiting kinetic energy. Potential energy is converted into kinetic energy. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy.
