Newton's Laws Examples

Front

What is Newton's 1st 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 2nd 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 3rd Law of Motion?

Back

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

Front

Example of Newton's 1st Law: A book resting on a table.

Back

The book will remain at rest until someone applies a force to move it.

Front

Example of Newton's 2nd Law: A car accelerating when the driver presses the gas pedal.

Back

The car's acceleration increases with more force applied and decreases with more mass.

Front

Example of Newton's 3rd Law: A rocket launching into space.

Back

The rocket pushes down on the ground with its engines, and the ground pushes the rocket upward.

Front

What does inertia mean in relation to Newton's 1st Law?

Back

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

Front

How does mass affect acceleration according to Newton's 2nd Law?

Back

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

Front

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

Back

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

Front

What is the significance of unbalanced forces in Newton's 1st Law?

Back

Unbalanced forces are necessary to change the motion of an object.
