###### Physics

Before diving into physics, you first need to understand the difference between scalar and vector quantities. Read a little about them on this website.

Use this simulation to play with position, velocity, and acceleration yourself! All you need to do in the Charts sections is type in a number for position, velocity, and acceleration, then watch the graphs create themselves! For even more fun, try changing the velocity/acceleration from positive to negative while the man is walking. What does that do?

Now that you know about the different types of energies, try answering these questions about roller coasters. Now the next time you go to an amusement park, you’ll be able to explain to your friends how energy is transferred on the rides!

Have you ever wondered why ice skaters twirl faster when they tuck themselves in? This webpage explains how angular momentum works, and even shows some really cool videos to help.

Professor Dave Explains (Video: Position, Velocity, Acceleration): Have you ever wondered what the difference between distance and displacement is? Or speed and velocity? Or even what acceleration really means? Check out this video, and you’ll learn more about the application of scalar and vector quantities.

Watch this video to understand Newton’s three laws of motion. By the end of it, you’ll be able to name an example of each one in use!

It's AumSum Time (Video: Kinetic and Potential Energy): Watch this fun video to learn about the Law of Conservation of Energy, kinetic energy, and (gravitational) potential energy, and how to notice them in our daily lives!

It's AumSum Time (Video: Static Electricity): Have you ever gotten shocked on a door handle? This is because of static electricity. Watch this video to find out what static electricity is, and try out their plastic comb + paper experiment at home!

Use this simulation to see how electrons move when rubbing a balloon on a sweater. Where are electrons transferring to a different object, and where are they just moving within an object? How does this relate to where the balloon is attracted?
