Mechanical Energy

Question 1

Gravitational potential energy

Answer 1

The energy an object possesses due to its position relative to a reference point

Question 2

Potential energy

Answer 2

Potential energy is the energy an object has due to its position or state

Question 4

Mechanical energy

Answer 4

The sum of gravitational potential energy and kinetic energy at a point

Question 5

The law of conservation of energy

Answer 5

The total energy in a system cannot be created nor destroyed, only transferred from one form to another

Question 6

The principle of conservation of mechanical energy

Answer 6

In the absence of air resistance or any external forces, the mechanical energy of an object is constant

Question 7

Kinetic energy

Answer 7

The energy an object has as a result of of the objects motion
