Current is defined as the flow of electrons. This flow is caused by the electrons within the wire being pulled by electric field. As the electrons travel through the wire they collide with the atoms that...
From the conservation of energy, we know that the change in gravitational potential energy (GPE) is equal to the change in kinetic energy (KE). GPE=mgh and KE=(1/2)mv^2. At the top of the slope, the car s...
As the bar magnet enters and exits the coil, there is a change in magnetic flux linkage through the coil. According to Faraday's law, an EMF is induced across the coil that is proportional to the rate of ...
Weight is the product of an object's mass and the dominant gravitational field that it feels. On Earth, objects feel a gravitational acceleration which is dependent on the mass of the earth and its rotati...
