a) Calculate the velocity of the red ball after the collision. b) Use kinetic energy to determine whether the collision was elastic or not.

The faster an object is travelling, the more energy there is in the kinetic energy store of the object. How fast the object is moving is its speed. Speed is measured in m/s. Velocity is speed in a ...

FIA President Max Mosely has sent a letter to Formula One teams outlining the plans for phasing in hybrid systems in the sport. Beginning in 2009, the Kinetic Energy Recovery System (KERS ...

Do you know the difference between potential and kinetic energy? I certainly don’t, which is why Dr. T, a Science Educator from the Springfield Museums, is with us ...
