Newtons Laws

Front

What does Newton's third law state?

Back

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

Front

What unit do we measure force in?

Back

Newtons (N)

Front

What is the Law of Inertia?

Back

It is Newton's first law, stating that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What are the appropriate units to describe acceleration?

Back

Meters per second squared (m/s²)

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 inertia?

Back

Inertia is 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 does the term 'net force' mean?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

As mass increases, acceleration decreases if the net force remains constant.

Front

What is an example of Newton's first law in everyday life?

Back

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