Applying Newton's first law to answer some true/false statements about why objects move (or not).

Use the dynamic worksheet to practice simplifying expressions with fractional exponents, rewriting them as radicals.

Why do astronauts appear weightless despite being near the Earth?

Figuring out the acceleration of ice down a plane made of ice.

Basics of gravity and the Law of Universal Gravitation.

This unit is about how things move along a straight line or, more scientifically, how things move in one dimension. Examples of this would be the movement (motion) of cars along a straight road or of trains along straight railway tracks.

Basic primer on Newton's First Law of motion.

In this section, you will:

• Evaluate square roots.
