Simple KE & PE Calculations

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy is the energy an object possesses due to its motion, calculated using the formula KE = 0.5 * m * v^2, where m is mass and v is velocity.

What is the formula to calculate Kinetic Energy?

Back

KE = 0.5 * m * v^2

Front

What is Potential Energy (PE)?

Back

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