Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second 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 (F = M*A).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the formula for calculating force?

Back

F = M*A

Front

What does inertia refer to?

Back

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

Front

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

Back

Newton (N)

Front

If a 10 kg object is accelerating at 5 m/s², what is the force acting on it?

Back

50 Newtons (F = M*A = 10 kg * 5 m/s²).

Front

What happens to a moving object if no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is an example of a force?

Back

A push or a pull on an object.

Front

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

Back

As mass increases, acceleration decreases if the force remains constant.
