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 stays in motion 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.

How many laws of motion did Sir Isaac Newton discover?

Back

Three.

Front

What does inertia refer to 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 is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion.

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

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

Back

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

Front

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

Back

As mass increases, acceleration decreases for a given force.
