What makes a rubber band car go fast?
You’ve given the rubber band potential (stored) energy. When it unwinds, this potential energy is transformed into kinetic (motion) energy, and the axle spins. The more you wind the rubber band, the more energy is available for your car’s wheels—and the farther and faster your car goes.
How do you make a rubber band car go?
Pull the rubber band and wrap the other end to the back underneath side of the 1/2” skewer and secure with glue. Carefully pull the car back, wrapping the rubber band around the back skewer, once tightly wound, let go and watch your car go!
What law explains how rubber band dragsters are propelled?
Introduce and demonstrate Newton’s Second Law of Motion using the K’NEX Rubber Band Powered Dragster.
Is stretching a rubber band push or pull?
The rubber band is being stretched out. The rubber band wants to push back to compress size that then creates a force that pulls both ends of then rubber band. In conclusion, tensional force is a force that pulls a wire, cable or string in two opposite directions.
Why are rubber bands stretched?
The reason rubber bands stretch is because when you pull on the rubber band, the polymers (which are normally coiled up more or less at random) get stretched lengthwise and the rubber band is lengthened.
How do you make a Lego car powered by a rubber band?
The basic design involves a pin that sticks up at the front of the car. Then a second pin is attached to the back axle. To make the car work, you’ll stretch a rubber band around both pins and then turn the back wheels to wind the rubber band around the back axle. Let go, and the car will zoom away!
Why does the car stop where did the energy go?
When your vehicle stops, the kinetic energy it has gained while in motion must go somewhere. If you are controlling the stop with your brakes, they will absorb the kinetic energy. When a vehicle stops abruptly, there is too much energy for the brakes to handle in the time allowed.
What happens when rubber band is stretched?
A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape. That is why a rubber band changes its shape even though it is a solid. Also, if excessive force is applied then the rubber band would break.
