Newton's Laws of Motion 2025

Front

What is Newton's First Law?

Back

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 does Newton's Second Law state?

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?

Back

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

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 motion.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

Which has more inertia: a bowling ball or a tennis ball?

Back

A bowling ball has more inertia than a tennis ball.

Front

If the force on an object is doubled, what happens to its acceleration?

Back

The acceleration is also doubled, according to Newton's Second Law.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

A book resting on a table will remain at rest until someone pushes it.
