Energy Flashcard

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is energy that has the potential to do work.

Front

How is work defined in physics?

Back

Work is defined as the product of force applied to an object and the distance over which that force is applied. It is calculated as Work = Force x Distance.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity, calculated as KE = 1/2 mv².

Front

What happens to energy during a transformation?

Back

During a transformation, energy changes from one form to another, such as potential energy converting to kinetic energy when an object is in motion.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, which is related to its temperature.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated as PE = mgh (mass x gravity x height).

Front

How does an archer demonstrate potential energy?

Back

An archer demonstrates potential energy by pulling back the bowstring, which stores energy in the bow.

Front

What occurs when an arrow is released from a bow?

Back

When an arrow is released, the potential energy stored in the bow is converted into kinetic energy, propelling the arrow forward.

Front

What is the relationship between kinetic energy and thermal energy?

Back

Kinetic energy can be transformed into thermal energy through friction or collisions, as seen when rubbing hands together.

Front

What is the formula for calculating work?

Back

The formula for calculating work is Work = Force x Distance, where force is measured in newtons and distance in meters.
