Newton's Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by an 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

If the force acting on an object is constant and its mass doubles, what happens to its acceleration?

Back

The acceleration decreases by half.

Front

What does the term 'mass' refer to in physics?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What happens to the acceleration of an object if the net force acting on it is increased?

Back

The acceleration of the object increases.

Front

Why is it harder to push a heavier object than a lighter one?

Back

Because the heavier object has more mass, which requires more force to accelerate.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, making it harder to start or stop moving.
