10 Newtons Laws

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. This is often expressed as F=ma.

What is Newton's 3rd Law of Motion?

Back

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

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What unit is used to measure force?

Back

The unit of force is the Newton (N).

Front

What does it mean for forces to be balanced?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What happens to an object when unbalanced forces act on it?

Back

An object will accelerate in the direction of the net force when unbalanced forces act on it.

Front

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

Back

As mass increases, acceleration decreases for a given force; they are inversely related.

What is inertia?

Back

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

Front

What is the relationship between action and reaction forces?

Back

Action and reaction forces are equal in magnitude and opposite in direction, acting on different objects.
