Newton's 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 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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

What is inertia?

Back

The resistance of an object to any change in its motion.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What does it mean for forces to be balanced?

Back

When two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

Give an example of unbalanced forces.

Back

A pencil falling off a desk when pushed is an example of unbalanced forces.

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

Back

As mass increases, acceleration decreases if the force remains constant.

What is the significance of the Law of Conservation of Momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

How does friction affect motion?

Back

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