How to make an object move back and forth ten metres? |
For my technology project mt group needs to make an object go forwards 10 metres hit against a wall and go back 10 metres, we cannot use remote control cars, it has to be built by us. What can i do?
btw, it has to have some kind of lightbulb light up on it…
The object will need is some kind of spring. When the object hits the wall its kinetic energy will be stored in the spring as potential energy, then released, pushing the object back to you.
The other key is to minimize friction. Any wheels have to spin very easily, and any tires must have a very low rolling resistance.
