Gravitational potential energy is measured in joules (J).
The formula for gravitational potential energy is Ep=21mv2.
Kinetic energy is given by the equation Ek=21mv2.
A skier with a mass of 70 kg traveling up a 300 m ski-lift gains gravitational potential energy of 210 kJ.
An ice skater with a mass of 50 kg traveling at 5 m/s has a kinetic energy of 125 J.
The principle of conservation of energy states that energy can be transferred but not created or destroyed.
When energy is transferred from kinetic to gravitational potential energy, the total energy remains constant.
The kinetic energy at the top of a thrown stone\’s flight is maximum.
The speed of a stone at the top of its flight is zero.
Mechanical work done by gravity converts gravitational potential energy to kinetic energy.
