Energy
... • One form of energy can turn into another form. • An example is when a ball is thrown (mechanical energy) against a wall, some of this energy is converted into sound and heat so the ball does not bounce back as far. • Most energy that is “wasted” in a transfer is converted to heat energy. ...

Kinetic Energy and Work
... We can use the equation above to define the SI unit for work (the joule, symbol: J ). An object of mass m = 1kg that moves with speed v = 1 m/s has a kinetic energy K = 1J Work: (symbol W) If a force F is applied to an object of mass m it can accelerate it and increase its speed v and kinetic energy ...
