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 an unbalanced 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. This is often expressed as the formula F = ma.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

Define inertia in the context of Newton's 1st Law.

Back

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

Front

What does the term 'force' mean in physics?

Back

A force is a push or pull on an object that can cause it to accelerate.

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 2nd Law, force equals mass times acceleration (F = ma).

Front

Give an example of Newton's 1st Law in everyday life.

Back

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

Front

What is an example of Newton's 2nd Law in action?

Back

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

Front

Explain the concept of action and reaction forces with an example.

Back

When you jump off a small boat, you push the boat backward (action), and the boat pushes you forward (reaction).
