SMS Newton's 3 Laws of Motion (2024-2025)

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 with the same speed and in the same direction unless acted upon by an unbalanced 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 is a force?

Back

A push or pull on an object.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What does inertia refer to?

Back

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

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

The object does not move.

Front

What is gravitational force?

Back

The force of attraction between two masses, such as the Earth and an object.

Front

What is the formula for calculating weight?

Back

Weight = mass × gravitational acceleration (W = mg).

Front

What is an unbalanced force?

Back

A force that causes an object to change its motion.
