Intro. Formulas Kinetic and Potential Energy

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How do you calculate gravitational potential energy?

Back

Gravitational potential energy (PE) is calculated using the formula: PE = mgh, where m = mass (kg), g = acceleration due to gravity (9.8 m/s²), and h = height (m).

Front

What is kinetic energy?

Back

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

Front

How do you calculate kinetic energy?

Back

Kinetic energy (KE) is calculated using the formula: KE = 1/2 mv², where m = mass (kg) and v = velocity (m/s).
