Kinetic and Potential Energy

Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of an object in motion, while potential energy is the stored energy of an object due to its position or state.

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 factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the mass of the object, the height above a reference point, and the acceleration due to gravity.

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

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

Back

Potential energy is highest at the highest points of the swing, where the pendulum is momentarily at rest.

Front

How does the conservation of energy principle apply to kinetic and potential energy?

Back

The conservation of energy principle states that energy cannot be created or destroyed, only transformed. In a closed system, the total energy (kinetic + potential) remains constant.

Front

What unit is used to measure energy and work?

Back

Energy and work are measured in Joules (J).

Front

How can you increase the gravitational potential energy of an object?

Back

You can increase gravitational potential energy by increasing the object's mass or raising its height above a reference point.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases because kinetic energy is directly related to the square of its velocity.

If a roller coaster car is at the top of a hill, what type of energy does it primarily have?

Back

At the top of a hill, a roller coaster car primarily has gravitational potential energy.
