What makes an object move? Well, when you ride a bike on a sunny day, the bike doesn't move by itself. Something makes the bike move. That something is called a force. A force can be a pull or a push. You are going to use what you already know and additional resources to demonstrate how force affect objects that are in motion. Once you are experts on forces and motion, you will become a ROLLER COASTER DESIGNER and create a roller coaster design using only a few materials. Let's Get Started!! Click on the Tasks link under Forces and Motion at the top and let's begin.
