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

By the end of this unit you will be able to:

• Understand when to use Venn diagrams.
• Draw Venn diagrams.
• Interpret Venn diagrams.

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.

This video explains how to plot straight line graphs.

This video looks at set notation, Venn diagrams and probability.

Speed necessary for the space station to stay in orbit.

Sometimes, when the probability problems are complex, it can be helpful to graph the situation. Tree diagrams and Venn diagrams are two tools that can be used to visualize and solve conditional probabilities.

This online lesson explores these two tools.
