The Science Behind Force and Motion

Getting To Know Force And Motion

Did you know that when you get on a teater totter, you are using a simple machine? You are! There are 6 simple machines, the wheel and axle, an inclined plane, a wedge, a screw, a lever, and a pulley. We use them to make our work easier to complete. To be able to use simple machines, you have to understand Newtons Laws of Motion! To use simple machines, you also have to use force and motion!

Simple Machines

There are 6 simple machines, the pulley, the screw, the wedge,an inclined plane, wheel and axle, and a lever. The pulley can have a chain, belt, or rope wrapped around a wheel so you can pull on it. The screw is an inclined plane that is wrapped around a cylinder. A wedge is an object that is thick at one edge and tapered to a thin edge at the other end. An inclined plane is a flat surface with one end higher than the other end. A wheel and axle is when a wheel is attached to a bar so they can rotate together. The last simple machine is a lever, the lever is a straight bar that pivots on or around a fulcrum. These are all 6 simple machines!

This is a video of myself and Kylee using a pulley to pull up blocks. Our pulley made the work easier!
