Unit 2.1 Study Guide

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What happens to particles when heat is added?

Back

The particles vibrate more as they gain energy from the heat.

Front

What type of energy is involved when heating food in a microwave?

Back

Radiation is the type of energy used in microwaves to heat food.

Front

At which point does a cart have the most mechanical energy?

Back

The cart has the same mechanical energy at all points if there are no external forces acting on it.

Front

What type of energy is produced when your body transforms chemical energy from food?

Back

The body transforms chemical energy into mechanical energy to enable movement.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

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