work and energy flashcard

Front

What happens to the energy of the ball as it falls from point B to D?

Back

The ball is losing potential energy and gaining kinetic energy.

Front

What type of energy transformation happens in a flashlight?

Back

Chemical energy --> light and heat energy.

Front

Work done = Force x _________

Back

Distance.

Front

Energy can not be created or destroyed, only converted from one form to another. True or False?

Back

True.

Front

What are the units for Kinetic Energy?

Back

J (Joules).

Front

Define Potential Energy.

Back

Potential energy is the energy stored in an object due to its position or configuration.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object due to its motion.

Front

State the formula for calculating Kinetic Energy.

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the principle of conservation of energy?

Back

The total energy in a closed system remains constant; energy can change forms but cannot be created or destroyed.

Front

What is the unit of work in the International System of Units (SI)?

Back

The unit of work is the Joule (J).
