Newtons laws

Front

What is Newton's 1st Law of Motion?

Back

An object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity 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. This is often expressed as the formula: F = ma (Force = mass x acceleration).

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction. This means that if one object exerts a force on another object, the second object exerts a force of equal strength in the opposite direction.

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: Pushing a car.

Back

If you push a car, the acceleration of the car depends on the force you apply and the mass of the car.

Front

Example of Newton's 3rd Law: Jumping off a small boat.

Back

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

Front

What does inertia refer to in 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

As mass increases, for the same amount of force applied, the acceleration decreases.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion (either starting, stopping, or changing direction).

Front

What is the relationship between force, mass, and acceleration?

Back

Force is the product of mass and acceleration; if you know any two of these variables, you can calculate the third.
