Newton's Laws of Motion

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 depends on the mass of the object and the amount of force applied. It can be expressed with 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.

Front

What is inertia?

Back

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

Front

Give an example of Newton's 1st Law of Motion.

Back

A soccer ball will not move until a player kicks it.

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 happens when two forces act in opposite directions?

Back

They cancel each other out, resulting in a net force of zero.

Front

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

Back

Force is directly proportional to the product of mass and acceleration.

Front

How does Newton's 3rd Law apply to walking?

Back

When you push down on the ground, the ground pushes you up with an equal and opposite force.

Front

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

Back

When a rocket launches, the engines push down on the ground, and the ground pushes the rocket upward.
