Newton's Laws of Motion Concepts

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What does Newton's Second Law of Motion state?

Back

F = ma (Force equals mass times acceleration).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What happens to an object in motion when no external force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, acceleration decreases if the force remains constant.

Front

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

Back

When you push against a wall, the wall pushes back with equal force.

Front

How does friction affect motion according to Newton's laws?

Back

Friction opposes motion and can change the state of an object's motion.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What does it mean when we say forces are balanced?

Back

Balanced forces result in no change in motion; the object remains at rest or moves at a constant speed.
