Velocity is speed in a particular direction. Velocity (v) is also measured in m/s. The more mass an object has, the more energy in the kinetic energy store. A runner with a mass of 60kg is running ...

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 ...

In classical physics the kinetic energy of bodies is calculated with the formula mass times speed squared. At the level of molecules this is not so simple, however, as project leader Fred Hamprecht ...
