What is Voltage? The measure of energy given to the charge flowing in a circuit. The greater the voltage, the greater the force or “pressure” that drives the charge…
What are the Causes of Friction? Friction is the force that two surfaces exert on each other when they rub against each other. Some Causes of Friction are: the strength of the…
Presentation on Friction Friction is a Force that always pushes against an object when it touches another object. When two things are in contact with each other, there will…
What is Force? A force is an influence on a system or object which, acting alone, will cause the motion of the system or object to change. If…
Electric Current Electric Current is a closed path through which electrons can flow. Electrons flow because of a difference in potential. When a switch is turned on it causes…
