Front

Which of Newton's laws of motion is illustrated by this picture? (universal gravity, inertia, F = m x a, action/reaction)

Back

inertia

Front

In class we used a spinning raw egg to demonstrate the law of ______________. The shell represented the _________________, while the liquid egg inside represented the ______________________.

Back

inertia, moving car, passengers

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is the formula for calculating force?

Back

F = m x a (Force = mass x acceleration)

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion; unbalanced forces do.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is acceleration?

Back

The rate of change of velocity of an object.
