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

As a student, you'll encounter vast amounts of information. Beyond academic material, you must process and interpret news, instructions, communications, and a wealth of other data. You'll also need to separate fact from opinion, and understand the quality of sources. The stronger your reading capabilities, the more efficiently and effectively you can turn information into knowledge.

• Describe a model for friction a molecular level.
• Describe matter in terms of molecular motion. The description should include: diagrams to support the description, how the temperature affects the image, what are the differences and similarities between solid, liquid and gas particle motion; how the size and speed of gas molecules relate to everyday objects.

Why do astronauts appear weightless despite being near the Earth?

Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity.

Basics of gravity and the Law of Universal Gravitation.

An overview of what physics is about as we delve deeper in future videos. How physics is related to math, the other sciences, and the world around us. 

In this course you will learn:

1. What logarithms are.
2. How to apply the log laws.
3. How to simplify logs.
4. How to solve log equations.

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.
