Front

What is geothermal energy?

Back

Thermal energy contained in and around magma that can be converted by a power plant into electrical energy.

Front

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

Back

Newton's 3rd Law of Motion.

Front

What happens to mechanical advantage if the resistance force is increased and the effort force is decreased?

Back

The mechanical advantage will increase.

Front

What is density?

Back

Density is the mass per unit volume of a material.

Front

When are you undergoing acceleration in a car?

Back

You are undergoing acceleration when you speed up, slow down, or make turns.

Front

What is the formula for calculating density?

Back

Density = Mass / Volume.

Front

What is the relationship between force, mass, and acceleration according to Newton's 2nd Law?

Back

Force = Mass x Acceleration.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

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