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

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 a net external 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. This is often expressed as 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 a force?

Back

A push or pull on an object.

Front

What is inertia?

Back

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

Front

What does it mean for an object to be in free fall?

Back

An object is in free fall when the only force acting on it is gravity.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What is the formula for calculating force?

Back

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

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
