Knowing Newton's 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 a net external 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 does inertia mean in the context of Newton's First Law?

Back

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

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

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

Back

Pushing a shopping cart: the harder you push (more force), the faster it accelerates.

Front

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

Back

When you jump off a small boat, you push the boat backward as you move forward.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

Force is the product of mass and acceleration; increasing mass requires more force to achieve the same acceleration.
