Where does the energy to wind the rubber band come from?
The energy to wind the rubber band comes from the mechanical force applied by stretching or twisting the band. As you stretch the rubber band, you're storing potential energy in its molecular structure. When you release the rubber band, this potential energy is converted into kinetic energy as the rubber band snaps back to its original shape.
When a rubber band is stretched it has what kind of energy?
Potential energy is converted into kinetic energy.
How do you harness elastic energy?
Elastic energy can be harnessed by stretching or compressing a material, such as a spring or rubber band, and then releasing it to allow it to return to its original shape. This release of stored energy can be used in various applications, such as in springs for mechanical systems or in elastic bands for shooting projectiles.
How do you build a Rubberband propelled car?
To build a rubber band propelled car, you will need a chassis (can be made of wood or lightweight plastic), wheels, rubber bands, a propeller (can be made of a straw or a wooden dowel), and something to wind up the rubber band like an axle. Attach the wheels to the chassis, wind up the rubber band around the axle, and attach the propeller. When you release the rubber band, it will unwind and propel the car forward.
How do you make a rubber band racer?
To make a rubber band racer, you will need a cardboard base, two straws for the axles, four bottle caps for wheels, a rubber band as the propulsion system, and a skewer to secure the rubber band. Simply connect the straws to the cardboard base, attach the bottle caps to the straws, secure the rubber band onto the skewer, wind it up, and watch your racer go!

When you wind a rubber band what kind of energy is used?
That is Potential energy

How do you make a car toy move without force and without using balloons?
One way to make a car toy move without force or balloons is by using a rubber band-powered mechanism. Wind up the rubber band by turning a key or winding a mechanism, and then let it unwind to provide the energy needed to move the car toy. As the rubber band unwinds, it will transfer its stored energy to the wheels of the car, propelling it forward.
Does wind affect rubber?
wind has no affect on rubber
How to make Elastic Band Powered Car?
You build a basic car, with a body and a way to support the front wheels and the back wheels. Each set of wheels should be firmly attached to an axle, maybe a piece of dowel, so that when the axle turns, so do the wheels. Then you need some way to attach the end of a strong rubber band to the middle of each axle so that when you rotate the wheels, the rubber band winds around the axle and stretches tight. You can do this with a small nail or screw put carefully through the dowel. The best way to wind the wheels is probably to push down on the car while you push the car along a surface, like carpet. once the rubber band is really tight, you let the car go, and the stored energy in the rubber band unwinds the axle, and off goes the car You don't have to have the band wind around both axles ... you could make it either just frontal drive or rear-wheel drive, but it probably goes better if you use both axles. You could also use two rubber bands, one for the front wheels and one for the back wheels, with the ends of each rubber band fixed to the middle of the car. Remember, the car will go fastest and the most distance if you use a really BIG strong rubber band, and can wind it up around the axles really really tight. But if you make it TOO tight or too strong, the car or the axles might break when you wind it up, which is not good and really annoying. Another way of making a car like this is to make it like the rubber-band powered toy airplanes. Make a light frame with 4 wheels, and buy a little toy propeller or take it off a toy airplane, then wind up the rubber band by winding the propeller. Then when you let go the propeller, it will drive the car along.
What are the energy transformations in a rubberband car?
Any body like a rubberband likes to stay in its state of equilibrium (a state of nirvana if you will). A rubberband car has a rubberband which when wound stores potential energy because it is now put in a state that is not its natural state of equilibrium. When you wind the rubberband the torque you supply from your hands stores potential energy in it. The moment this woundup rubberband is released, it craves to get to its state of equilibrium and in doing so expends its potential energy. If there are proper linkages to the wheels of a toy car, then this potential energy can be directed to the wheels. The potential energy gets converted into kinetic energy and the wheels rotate. Recognize that all of the potental energy is not converted into kinetic energy that is wholly used the motion of the toy. There are heat losses, friction losses in the linkages etc. These are small in comparison to the friction of the surface on which the toy runs. This leads the kinetic energy to be slowly used in overcoming the frictional forces of the surface and the kinetic energy finally depletes to zero when the toy stops.
