What is the acceleration due to gravity at the space station.

In this unit you will learn how to identify equivalent metric units of capacity.

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?

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.

In this section, you will:

• Evaluate square roots.
• Use the product rule to simplify square roots.
• Use the quotient rule to simplify square roots.
• Add and subtract square roots.
• Rationalize denominators.
• Use rational roots.

Speed necessary for the space station to stay in orbit.

Outcomes

By the end of this course you will:

• Be able to define capacity and volume
• Be familiar with the metric units of capacity
• Be able to convert from one unit of capacity to another
