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

When electromagnetic radiation is absorbed by a material the energy it carries has to go somewhere. When lower energy waves, like radio and infrared waves, are absorbed there can be an increase in temperature of the absorbing material. Higher energy waves, like x-ray and gamma waves, can actually permanently damage or change materials. Learn about the different types of electromagnetic waves and how their energies can influence their effects on objects.

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

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.

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

Viewing g as the value of Earth's gravitational field near the surface rather than the acceleration due to gravity near Earth's surface for an object in freefall.

An explanation of wave interference and solution of a few examples to find the value of the total wave when two wave pulses overlap
