8.6C Newton's Laws of Motion

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 unbalanced force.

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

Define inertia.

Back

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

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m).

Front

How does mass affect acceleration?

Back

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

Front

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate.

Front

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

Back

A passenger lurches forward in a car when it suddenly stops.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

Explain the concept of action-reaction pairs with an example.

Back

When a rocket expels gas downwards, the gas pushes the rocket upwards.
