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 = m x a.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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 = m x a represent?

Back

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

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

Give an example of Newton's 3rd Law of Motion.

Back

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

Front

What is the significance of the term 'net force'?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

How does Newton's 1st Law apply to a seatbelt in a car?

Back

A seatbelt helps to stop a passenger from continuing to move forward when the car suddenly stops, demonstrating inertia.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
