8.6(C): 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 at a constant velocity unless acted upon by a net external force.

Front

What does the term 'inertia' mean?

Back

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

Front

What happens when two objects collide according to Newton's Third Law?

Back

They exert equal and opposite forces on each other.

Front

What is the formula for calculating force?

Back

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

Front

What is an example of an object at rest?

Back

A soccer ball lying on the ground.

Front

What is an example of an object in motion?

Back

A car driving down the street.

Front

What is the relationship between mass and acceleration?

Back

For a given force, an increase in mass results in a decrease in acceleration.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, causing them to slow down or stop.

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.

Front

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

Back

A heavier object requires more force to move than a lighter object.
