Tangential and radial acceleration are both types of linear acceleration. Tangential acceleration is the rate of change of the tangential velocity and arises when the speed around the circle is not constant; radial acceleration will always be present (including for constant speeds) and points to...
The work done on an object to move it a distance x in the direction of the force applied is Fx. F = ma and a = (v-u)/t ; we also know that x = 1/2 (u+v) t since this is just the average velocity multiplied by time.
Work done = energy transferred = kinetic energy gained. This is m(v-u)/t * 1/2...
I understand that in an electrical circuit, a positive test charge will gain electrical potential energy when moving from the negative to positive terminal of a battery (as it's moving against the electric field); it will then naturally flow around the circuit back to the negative terminal as it...
