Newton's Laws of Motion

Front

What causes a rocket to launch?

Back

An opposite reaction.

Front

Can a still object have forces acting upon it?

Back

Yes, a still object does have forces acting upon it.

Front

What type of force is needed to move objects of larger mass?

Back

More force is needed.

Front

What does Newton's third law state about action and reaction?

Back

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

Front

What must act on an object for its motion to change?

Back

A force must act on it.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

The greater the mass of an object, the more force is needed to accelerate it.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.
