Newton's Laws of Motion Concepts

Front

What is Newton’s First Law of Motion?

Back

An object in motion will stay in motion unless acted upon by an external force.

Front

What is Newton’s Second Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied.

Front

What is Newton’s Third Law of Motion?

Back

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

Front

What happens to an object’s motion if balanced forces are acting on it?

Back

Its motion remains unchanged.

Front

What unit is used to measure force?

Back

Newton.

Front

If a person pushes a box with 10 N of force, and the force is doubled, what happens to the acceleration?

Back

The acceleration will double.

Front

What is inertia?

Back

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

Front

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

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m*a).

Front

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

Back

When a rocket launches, the engines push down on the ground, and the rocket moves upward.
