Newton's 3 Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as F=MA.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does F=MA stand for?

Back

Force = Mass x Acceleration.

What is the unit of force in the International System of Units (SI)?

Back

Newton (N).

Front

If a 10 kg object is accelerated at 2 m/s², what is the force applied?

Back

20 N (Force = Mass x Acceleration = 10 kg x 2 m/s²).

Front

What happens to an object in motion if no external forces act on it?

Back

It continues to move at a constant velocity.

Front

What is inertia?

Back

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

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.
