Newton's Laws of Motion

Front

What is Newton's 1st Law of Motion?

Back

An object in motion will stay in motion unless acted upon by an unbalanced force, and an object at rest will stay at rest 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).

What is Newton's 3rd Law of Motion?

Back

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

How does mass affect the motion of an object according to Newton's 2nd Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

What is 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

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

Back

A passenger in a car lurches forward when the car suddenly stops.

Front

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

Back

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

Front

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

Back

When a swimmer pushes water backwards, they move forward due to the reaction force of the water pushing them.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.

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

Back

It continues to move at a constant velocity.
