Kinetic and Potential Energy

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Potential Energy is the stored energy in an object due to its position or state. It is commonly associated with gravitational potential energy, calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

KE = 1/2 mv², where m is mass and v is velocity.

PE = mgh, where m is mass, g is acceleration due to gravity (approximately 9.81 m/s²), and h is height.

0 J (zero joules) because it is at ground level.

At the lowest point of the dive, where the diver has the least Potential Energy.

0.45 J (using KE = 1/2 mv²: KE = 1/2 * 0.1 kg * (3 m/s)² = 0.45 J).

0.98 J (using PE = mgh: PE = 0.1 kg * 9.81 m/s² * 1 m = 0.98 J).

25.5 J (using PE = mgh: PE = 2 kg * 9.81 m/s² * 1.3 m = 25.5 J).

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.
