Newton's Laws of Motion

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, expressed as F=ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

What does the term 'inertia' refer to in physics?

Back

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

Front

What is a force?

Back

A force is a push or pull acting upon an object.

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 state of motion.

Front

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

Back

According to Newton's 2nd Law, force equals mass times acceleration (F=ma).

Front

Can an object be in motion if no forces are acting on it?

Back

Yes, according to Newton's 1st Law, an object in motion will continue to move at a constant velocity if no net external forces act on it.

Front

What is an example of Newton's 3rd Law of Motion?

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 2nd Law?

Back

The net force is the total force acting on an object, and it determines the object's acceleration.
