Newton's Third Law

Front

What is Newton's Third Law of Motion?

Back

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

Front

Define action and reaction forces in Newton's Third Law.

Back

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

Front

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

Back

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

Front

What is the significance of action-reaction pairs?

Back

They explain how forces interact between two objects and are fundamental to understanding motion.

Front

How does Newton's Third Law apply to rocket propulsion?

Back

Rockets propel forward by expelling gas backward, creating an equal and opposite reaction that pushes the rocket forward.

Front

What is inertia and how does it relate to Newton's laws?

Back

Inertia is the tendency of an object to resist changes in its state of motion, which is explained by Newton's First Law.

Front

Explain the concept of equilibrium in relation to forces.

Back

An object is in equilibrium when the net force acting on it is zero, meaning all forces are balanced.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

How do action-reaction forces affect motion?

Back

They do not cancel each other out because they act on different objects, allowing both to move.

Front

What role do frictional forces play in Newton's Third Law?

Back

Frictional forces are action-reaction pairs that oppose motion, affecting how objects move relative to each other.
