Newton's Three Laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

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

What does Newton's Second Law of Motion state?

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.

Give an example of Newton's First Law of Motion.

Back

A book resting on a table will remain at rest until someone pushes it.

Front

How does inertia affect passengers in a car when it suddenly stops?

Back

Passengers lurch forward due to inertia, as their bodies tend to continue moving in the direction of the car's motion.

Front

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

Back

As mass increases, acceleration decreases for a given force.

Front

Provide an example of Newton's Third Law of Motion in everyday life.

Back

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

What is the significance of the net force in Newton's First Law?

Back

The net force determines whether an object will change its state of motion.
