Newton's 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 continues in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What does Newton's 2nd Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

Inertia is the tendency of an object to resist changes in its state of motion, which is the basis of Newton's 1st Law.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A ball thrown in space continues to move in a straight line at constant speed.

Front

What is the formula for calculating force according to Newton's 2nd Law?

Back

Force (F) is calculated as mass (m) multiplied by acceleration (a): F = ma.

Front

Can you give an example of Newton's 3rd Law of Motion?

Back

When you paddle a kayak, you push the paddle backwards in the water, and the kayak moves forward.

Front

What is the significance of the net force in Newton's 2nd Law?

Back

The net force is the total force acting on an object, and it determines the object's acceleration.

Front

How does Newton's 3rd Law apply to a rocket launch?

Back

As the fuel in a rocket ignites, the force of gas expansion pushes out the back of the rocket, propelling it forward.

Front

What happens to a boat when a person steps off it?

Back

The boat moves backwards as the person moves forwards, demonstrating Newton's 3rd Law.
