8th Grade Energy flashcard

Front

Energy due to motion is ____________ energy.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is the process of heat transfer through direct contact called?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

True or False: Newton's 2nd law states that an object at rest will stay at rest unless acted upon by a force.

Back

False. This statement describes Newton's 1st law.

Front

What happens to the molecules of a substance when heat is transferred through conduction?

Back

They move faster and collide more frequently.

Front

Which of Newton's laws states that for every action, there is an equal and opposite reaction?

Back

This is Newton's 3rd law.

Front

What is potential energy?

Back

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

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves.

Front

What does Newton's 1st law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.
