How is potential energy calculated for an object at height?

Back

Potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What factors affect kinetic energy?

Back

Kinetic energy is affected by the mass of the object and its velocity, calculated using the formula KE = 1/2 mv².

What is the relationship between potential energy and kinetic energy in a closed system?

Back

In a closed system, the total mechanical energy (potential + kinetic) remains constant, assuming no external forces do work.

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.
