Newton's Laws of Motion

Front

What does Newton's First Law state about an object at rest?

Back

An object that is not moving will stay at rest unless acted upon by an external force.

Front

What is inertia?

Back

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

Front

Which has more inertia: a feather or a hammer?

Back

A hammer has more inertia than a feather.

Front

What does Newton's Second Law state?

Back

Newton's Second Law states that 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 an example of Newton's Third Law?

Back

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

Front

Which has less inertia: a bowling ball or a tennis ball?

Back

A tennis ball has less inertia than a bowling ball.

Front

What is the formula for calculating force according to Newton's Second Law?

Back

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

Front

What is the significance of mass in Newton's Laws?

Back

Mass is a measure of an object's inertia and affects how much force is needed to change its motion.

Front

How does friction relate to Newton's First Law?

Back

Friction is a force that opposes motion and can prevent an object at rest from staying at rest.

Front

What is an example of an object in motion that illustrates Newton's First Law?

Back

A soccer ball rolling on a field will continue to roll until friction or another force stops it.
