Potential and Kinetic Energy

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating gravitational potential energy?

Back

The formula for gravitational potential energy (GPE) is GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

How does mass affect kinetic energy?

Back

Kinetic energy is directly proportional to mass; as mass increases, kinetic energy increases if velocity remains constant.

Front

How does height affect potential energy?

Back

Potential energy is directly proportional to height; as height increases, potential energy increases if mass remains constant.

Front

What is the relationship between kinetic energy and velocity?

Back

Kinetic energy is proportional to the square of velocity; if velocity doubles, kinetic energy increases by a factor of four.

Front

What type of energy does a person climbing a ladder possess?

Back

A person climbing a ladder possesses both kinetic energy (due to movement) and potential energy (due to height gained).

Front

What happens to an object's potential energy when it falls?

Back

When an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).
