Newtons Laws

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. This is often summarized by the formula F = ma.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What unit is used to measure force?

Back

Newtons (N).

Front

What happens to an object when the net force acting on it is zero?

Back

The object remains at rest or continues to move at a constant velocity.

Front

What is inertia?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.

Front

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

Back

According to Newton's Second Law, force equals mass times acceleration (F = ma).

Front

What is an example of Newton's First Law in everyday life?

Back

When a car suddenly stops, passengers lurch forward due to inertia.

Front

What is an example of Newton's Second Law in action?

Back

A heavier object requires more force to accelerate than a lighter object.
