PS 3.2 - Potential & Kinetic Energy Transformation

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the edge of a cliff has potential energy.

Front

How does kinetic energy change as an object speeds up?

Back

As an object speeds up, its kinetic energy increases.

Front

How does potential energy change as an object falls?

Back

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

Front

What happens to the total energy of a system when energy transforms from potential to kinetic?

Back

The total energy of the system remains constant; it transforms from potential energy to kinetic energy.

Front

What is the relationship between height and potential energy?

Back

The higher an object is, the more potential energy it has due to its position.

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 potential energy?

Back

The formula for 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 at the highest point of a pendulum swing?

Back

At the highest point of a pendulum swing, potential energy is at its maximum.

Front

What happens to kinetic energy at the lowest point of a pendulum swing?

Back

At the lowest point of a pendulum swing, kinetic energy is at its maximum.
