Force and Motion

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What force pulls objects toward the Earth?

Back

Gravity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its motion.

Front

What happens to an object at rest when no outside force acts on it?

Back

It remains at rest.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the greater the gravitational force acting on it.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).
