Identification: Newton’s 3 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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is inertia?

Back

The tendency of an object to resist a change in its state of motion.

Front

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

Back

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

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a)

Front

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

Back

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

Front

What does it mean when we say 'action and reaction' in Newton's 3rd Law?

Back

It means that forces always occur in pairs; if one object exerts a force on another, the second object exerts a force of equal magnitude and opposite direction on the first.

Front

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

Back

If the mass increases and the force remains constant, the acceleration decreases.

Front

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

Back

A heavier vehicle requires more force to accelerate than a lighter vehicle.
