Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object has due to its position in a gravitational field, typically related to its height and mass.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

At which point in a pendulum's swing is potential energy highest?

Back

Potential energy is highest at the highest points of the swing.

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the formula for 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 gravitational potential energy?

Back

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

Front

What happens to potential energy as an object falls?

Back

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

Front

What is the relationship between kinetic energy and mass?

Back

Kinetic energy is directly proportional to the mass of the object; if mass increases, kinetic energy increases.
