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 with the same speed and in the same direction 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)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is an unbalanced force?

Back

A force that causes an object to change its state of motion (acceleration).

Front

What is a balanced force?

Back

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

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 1st Law of Motion.

Back

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

Front

What happens to acceleration when the force is tripled while mass remains constant?

Back

The acceleration triples.

Front

What is the formula for calculating force?

Back

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