Science Toy :: essays research papers

My rook, is a toy auto that bounces and also drives forward and in reverse. It is called Hop-Along-Impala. I built it by taking a toy car that I owned, which already hopped in front and back by using a series of jaggy gears connected to a go. Then I went and bought another motor so I could make the car go forward and hop and go in reverse and not hop. I first took a mates of wire curtailters and cut off a piece of plastic attached to the rear wheels so it would disable them from bouncing. Then I took a racy glue gun and glued the piece of plastic, that I previously cut off, on so that the wheels would remain level. Then I glued the motor that I attached to the other motor and glued it close to the tucker so that it would make contact so that the wheel would turn.When I commove the button on the remote up the car moves forward because when I push it, it completes a circuit so electrons can flow, thus send power to the motors in the car. That is how power gets from the batte ries to the motors in the car. But how does a electric battery work? A battery has a negative electrode and a electropositive electrode. An electrolyte paste separates the two electrodes and causes a chemical response between them. This reaction causes a current to flow and electrons move through a managing director that connects the positive and negative electrodes.When the power get to the motors, they convert the electrical efficiency into mechanical energy. Inside the motors a current is passed through the armature and a tortuosity is made by a magnetic reaction, and the armature spins. The action of the commutator and the connections of the field coils of motors be the same as those used for generators. The revolution of the armature induces a potential in the armature windings. This induced voltage is opposite in direction to the outside voltage applied to the armature, and thus is called back voltage or counter electromotive force.When the car is bounced up onto the air, it falls down because of gravity. Gravity is the force that everything on creation possesses and it tends to draw objects closer to one another. Gravity is one of the four native forces of nature. Unlike electromagnetism, gravity doesnt have repulsive
