Newton's Laws

Front

What is Newton's First 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 Second 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 Third Law of Motion?

Back

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

Front

What does 'balanced forces' mean?

Back

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

Front

What does 'unbalanced forces' mean?

Back

Forces that are not equal and opposite, 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

What is the formula for calculating force?

Back

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

Front

What happens to an object's motion when the net force is zero?

Back

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

Front

What is the relationship between force and acceleration?

Back

As force increases, acceleration increases, provided mass remains constant.

Front

What is an example of Newton's First Law in everyday life?

Back

A skateboarder continues to roll until friction or another force stops them.
