Newton's Laws

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 the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Define inertia in the context of Newton's 1st Law.

Back

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

Front

What does the formula F = ma represent?

Back

It represents Newton's 2nd Law of Motion, where F is force, m is mass, and a is acceleration.

Front

Give an example of Newton's 1st Law in everyday life.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How does Newton's 2nd Law apply to a car accelerating?

Back

The greater the force applied to the car, the greater its acceleration, assuming the mass remains constant.

What is an example of Newton's 3rd Law in action?

Back

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

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

Back

As mass increases, acceleration decreases for a given force.

How does friction relate to Newton's 1st Law?

Back

Friction is an unbalanced force that can cause an object in motion to slow down or stop.
