The Trebuchet Challenge | Space Time
Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

7 Myths About Movement
Bumblebees fly, lights turn on, and you can ride a bike without falling over. We all know these things to be true, but what you may not know is the real reason behind why they work. Join Olivia to bust seven myths about motion.

Why Do Golf Balls Have Dimples?
The size, shape, and designs of the balls used in sports are usually the results of decades or even centuries of trial and error, and the cute, dimply li'l golf ball is no different!

Free Body Diagrams
Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.

Gravity Compilation
Maybe you'd like to just hear about one topic for a while. We understand. So today, let's just watch some videos about Gravity. We'll learn about why we don't fly off into space, what mass has to do with it, how does air resistance work,...

Free-Body Diagrams
In this video Paul Andersen explains how free-body diagrams can be used to solve kinematics problems. The only two parts of a free-body diagram are the object and all external forces acting on the object. Numerous situations are...

Danger! Falling Objects
So, what would happen if you dropped a hammer and a feather at the same time, from the same height? Well, the hammer would hit the ground first, right? But why? You might think it's because the hammer is heavier, or has more mass than...

Position, Velocity and Acceleration
In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Newton's Three Laws of Motion
Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.

The ONE thing your teacher is NOT telling you that will simply forces!
Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...
