    Okay, pretty interesting that induction makes an object have an electric charge on the one hand, and attracts it aswell. Thank you very much!

    So, when you bring a charged object near for example a soda can, I get that the soda can gains a positive side and a negative side, but the can also moves towards the charged object, why is that? Is it because if you put a negative charged object near the soda can the side of the can nearest to...

    Hi So I am busy studying rotational motion and there's an example in the book where they explain that when a car brakes the force of friction acts as a torque force which explains why a car lifts up at the back when braking. Because the car does no rotational motion they say the net torque is...
