Newtons laws

Front

What is Newton's 1st 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 an external force.

Front

What is inertia?

Back

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

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 = m x a).

Front

What does the equation F = m x a represent?

Back

It represents Newton's 2nd Law of Motion, where F is force, m is mass, and a is acceleration.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

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

Back

A soccer ball remains at rest until a player kicks it.

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the relationship between action and reaction in Newton's 3rd Law?

Back

For every action force, there is a reaction force that is equal in size and opposite in direction.

Front

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

Back

Pushing a shopping cart versus pushing a car; the cart accelerates more easily due to its lower mass.

Front

What does it mean when we say 'force is a vector quantity'?

Back

It means that force has both magnitude and direction.
