Unit 6: Newton's 3 Laws

Front

What is the term for an object's resistance to changes in motion due to its mass?

Back

Inertia

Front

According to Newton's 2nd Law, what happens to acceleration if mass increases?

Back

Acceleration decreases.

Front

What is the reaction force when a swimmer pushes water backward?

Back

The water moving the swimmer forward.

Front

Why can't you see the Earth's movement when you jump up and push it down?

Back

The Earth barely moves due to its greater mass.

Front

In the presence of unbalanced forces, in which direction will an object move?

Back

In the direction of the larger force.

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 unless acted upon by a net external force.

Front

What does Newton's 2nd Law state about the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F = ma).

Front

What is the principle of action and reaction as stated in Newton's 3rd Law?

Back

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

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force according to Newton's 2nd Law?

Back

F = ma (Force equals mass times acceleration).
