Newtons Laws

Front

What is Newton's 1st Law of Motion?

Back

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside 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 (F=ma).

Front

What is Newton's 3rd 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 1st Law?

Back

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

Front

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

Back

Force equals mass times acceleration (F=ma).

Front

What happens when forces are balanced?

Back

When forces are balanced, there is no change in motion; the object remains at rest or continues to move at a constant velocity.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

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

Back

Yes, an object can be in motion if no net forces are acting on it, due to inertia.

Front

What is an example of Newton's 1st Law in everyday life?

Back

A soccer ball will not move until a player kicks it.

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.
