1.Define potential energy? Give the formula in computing potential energy

• P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

2.What is Kinetic energy? Give the formula in computing kinetic energy

• K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

3.Enumerate the factors affecting Potential and Kinetic energy*

• Due to gravity, kinetic energy is affected by the object's mass and velocity.
