Newton's Laws

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 with the same speed and in the same direction unless acted upon by a net 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 Second 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 Third Law of Motion?

Back

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

Front

What does it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

Give an example of Newton's First Law in action.

Back

A magician pulls a tablecloth from under dishes without moving them, demonstrating that the dishes remain at rest due to inertia.

Front

What is the formula for calculating force?

Back

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

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 applied.

Front

What is the relationship between action and reaction forces?

Back

Action and reaction forces are equal in size and opposite in direction, acting on different objects.

Front

What is an example of Newton's Third Law?

Back

When you jump off a small boat, you push the boat backward as you move forward.
