What is the acceleration due to gravity at the space station.
What is the acceleration due to gravity at the space station.
By the end of this unit you will be able to:
These two short online tutorials discuss how the earth rotates and then the earth's revolutions.
In the first URL, the YouTube video explains why earth has spring, summer, autumn and winter seasons. The second URL summarizes the key takeaway points.
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 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.
