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 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. (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 'unbalanced forces' mean?

Back

Forces that are not equal in size and opposite in direction, resulting in a change in motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

A larger mass requires a greater force to achieve the same acceleration as a smaller mass.

Front

What is the formula for calculating force?

Back

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

Front

What happens to an object when forces are balanced?

Back

The object remains at rest or continues to move at a constant velocity.

Front

Can an object be in motion if no forces are acting on it?

Back

Yes, an object can continue moving at a constant velocity if no net forces act on it.

Front

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.
