Newtons 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 a net external 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 F=ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What does the term 'force' mean in physics?

Back

A force is a push or pull on an object that can cause it to accelerate.

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

Can you give an example of Newton's 1st Law?

Back

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

Front

What is inertia?

Back

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

Front

How does Newton's 3rd Law apply to walking?

Back

When you push down on the ground with your foot, the ground pushes you up with an equal force, allowing you to walk.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is an example of Newton's 2nd Law in action?

Back

A heavier cart requires more force to accelerate than a lighter cart.
