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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. The more mass an object has, the more inertia it has.

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. This is often expressed as the formula F = ma.

Front

What does the formula F = ma represent?

Back

F represents force, m represents mass, and a represents acceleration. It shows how force, mass, and acceleration are related.

Front

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

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What does it mean for forces to occur in pairs?

Back

It means that when one object exerts a force on another, the second object exerts a force of equal size but in the opposite direction on the first object.

Front

What is an example of Newton's Third Law in everyday life?

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion, resulting in acceleration.
