Why do astronauts appear weightless despite being near the Earth?

Basics of gravity and the Law of Universal Gravitation.

Introduction to passive and active transport

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.

Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.

Outcomes

In this unit you will learn that: 

• Osmosis is the movement of a liquid from an area of high concentration to an area of low concentration until it reaches equilibrium.
