Purpose
The Fundamental purpose of the Pitching Machine is to deliver a pitch to an awaiting batter in the strike zone at a certain speed.

Energy
Some energy transformations are from when I plug it in to the outlet, it makes two wheels spin making kinetic energy.

Controls
The sensors and controls in this device are when the baseballs are waiting to be pitched, they are all in a line, one behind the other. When the batter is ready to bat, he/she puts a token in the machine and then it sends a message to a timer which is set in conjunction with a metal bar across the baseballs which lets one ball go to the wheels at a time.

Materials
Some materials that are essential to the device are: the bar that holds the baseballs back, the sensor, the two wheels, and the rubber wheels propelled by the motor.

Science
The scientific principle central to the operation is from electricity to the coil to make an electromagnet that makes the wheel and axle rotate, thus making the rubber wheels rotate. If the North magnet is on the left side of the motor on the wheel spinning counter clockwise, North must be on the right side of the motor on the wheel spinning clockwise.

Design
The typical device looks like two motors with wheels on the wheel and axle. The wheels are made out of rubber that can be any color. Coming into the machine are baseballs on, pretty much, an escalator that drops the baseballs off.

Evolution
What changes have there been (or could there be) in this device? Some changes that could be made to this device are to make this device smaller. Just make the wheels be like normal but then put the, "escalator", closer to the wheels.

Competitors
A device that serves a similar purpose is a baseball connected to a long plastic stick connected to a pole that swings bck and forth.

Partners
A device that works in conjunction with the pitching machine is the portable pitching machine.
