Front

What is the principle of balanced forces?

Back

If an object is hit on opposite sides with the same amount of force, the forces cancel out and the object will not move.

Front

What two factors affect the force of gravity between two objects?

Back

Mass and distance.

Front

Define mass.

Back

The amount of stuff that makes up something.

Front

What is acceleration?

Back

A change in speed or direction of something.

Front

What type of energy transformation occurs in a windmill?

Back

Mechanical energy is transformed into electrical energy.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is potential energy?

Back

The stored energy of an object due to its position or state.
