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 at a constant velocity 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 (F=ma).

What is Newton's 3rd Law of Motion?

Back

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

What does 'net force' mean?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, causing a change in an object's motion.

Front

Give an example of inertia in everyday life.

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.

What is the formula for calculating force?

Back

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