states that

A 60 kg dilver at an initial height of 5m leaps off the board to fall freely into the water. when he reaches a height of 1m above the water calculate his velocity.assume negligible air resistance. initial P.E = P.E at 1m +K.E at 1m (60)*(10)*(5)= (60*10*1)+(1/2*60*v*v) Therefore, V = (8.94) m/s

Gravitational potential energy

include

Chemical potential energy

Energy that flow from a refgion of higher to lower temprature

energy produced when object vibrate

Energy that enable us to see

Energy a body has due to its motion

1/2 * mass (kg) * Velocity (m/s) *Velocity (m/s)

A 60kg man running at a speed of 10 m/s will have a kinetic energy of 1/2 * 60 * 10 * 10 = 3000 J

Energy that result from the flow of charged particle (electron)

Power (W) * Time (s)
