07) 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 with the same speed and in the same direction 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

What is friction?

Back

A force that opposes the motion of an object.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass × gravitational acceleration (W = mg).

Front

What happens to the forces during a collision?

Back

In a collision, the forces exerted by the objects on each other are equal in magnitude and opposite in direction.

Front

What is the significance of the net force?

Back

The net force is the total force acting on an object, determining its acceleration.

Front

How does mass affect acceleration?

Back

A larger mass results in less acceleration for the same amount of force applied (F = ma).

Front

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

Back

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