Newton's 3rd Law

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is an example of Newton's 3rd Law in action?

Back

When a swimmer pushes the water backward, the water pushes the swimmer forward.

Front

What is the definition of tension force?

Back

Tension force is the force transmitted through a string, rope, or wire when it is pulled tight by forces acting from opposite ends.

Front

How do action-reaction forces work?

Back

Action-reaction forces are pairs of forces acting on two different objects; they do not cancel each other out because they act on different bodies.

Front

What happens to a rocket when it expels gas downward?

Back

The rocket moves upward due to the reaction force from the expelled gas, demonstrating Newton's 3rd Law.

Front

What is the formula to calculate force?

Back

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

Front

If a 10 kg object accelerates at 15 m/s², what is the force applied?

Back

150 Newtons.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, such as the Earth and an object.

Front

What is the difference between tension and gravitational force?

Back

Tension is a pulling force transmitted through a rope or string, while gravitational force is the attraction between two masses.

Front

Why do action-reaction forces not cancel each other out?

Back

Because they act on different objects.
