Rubber Band Car Designs For Speed

Loop one end on the hook at the front of the car and loop the other end over the catch on the rear axle.

Rubber band car designs for speed.

Corrugated cardboard two drinking straws two wooden skewers four cds that are okay to get scratched sponge paper clip assorted rubber bands tape scissors flat hard surface for testing your car hot glue gun optional. There are lots of creative rubber band car ideas but you definitely need a rubber band and a way to wind it up. How does it work. When you turn the axle on the car you are giving the rubber band potential energy which is stored energy.

Turn the rear axle several times to wind the rubber band around it set the car on a smooth hard surface and let go. The video below shows a thirty foot run would have been longer but the trans. Your car is ready to roll. Choose a large rubber band to power the car.

Legos cardboard and other household items are used. Wind the rubber band around the axle. The aim of this project is distance. With this you can design the car to speedily sprint a short distance or travel a long distance.

Because the rubber bands in this tricycle style assembly rotate in the same axis as the wheel it is possible to rotate the drive wheel dozens of times per rubber band. Anything below 20 meters is a failing grade. When the rubber band unwinds and the axle spins it transforms the potential stored energy into kinetic energy or motion. Loop the loose end of the rubber band over the catch.

Students must design their cars to travel in a straight line for a distance of at least 3 meters within a 1 meter wide track. Plus it s even more fun if you can make a car go without just pushing it or by adding an expensive motor. This rubber band powered car is an awesome engineering activity for your next stem project time. The focus of this lesson is on rubber band powered car design.

6 rubber band car designs use a body axle and wheels to teach potential and kinetic energy. Kids love building things that move. On twisting the rubber band around the axle you are storing potential energy in it that gets transformed into kinetic energy when you let it go. It must travel at least 20 meters and best of all is above.

Toothpicks straws and bottle caps constitute this unique design of rubber band race car. Long distance rubber band car. Teams of students construct rubber band powered cars from everyday materials.
