Work and Energy Unit Review 23-24

Front

What is work in physics?

Back

Work is done when a force causes an object to move in the direction of the force. It is calculated as Work = Force x Distance.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball at the top of a hill has potential energy.

Front

What is the principle of energy transformation?

Back

Energy can change from one form to another, such as potential energy transforming into kinetic energy when an object moves.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, often associated with heat.

Front

What is the relationship between heat and thermal energy?

Back

Heat is the transfer of thermal energy from one object to another due to a temperature difference.

Front

What is an example of potential energy?

Back

A ball sitting on a mountaintop has potential energy because of its height.

Front

What is an example of kinetic energy?

Back

A rollercoaster traveling along the track is an example of kinetic energy as it is in motion.

Front

At which point is potential energy greatest in a rollercoaster?

Back

Potential energy is greatest at the highest point of the rollercoaster.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 x mass (m) x velocity (v)².
