(Using diagrams to aid explention)This is a common difficulty students with Newton's third law, because in isolation it makes sense; If i am pushing a cart, and the cart imparts an equal amount of force o...

This question is relating to the balancing of forces on a moving object.
The force on the skydiver will be equal to its weight multiplied by its acceleration (the acceleration will be equal to 9.8m/s...

It is important to understand that Q=It and therefore by rearranging the equation we know that 1 amp means one coulomb of charge passing through a point every second in the circuit. Therefore we multiply ...

We apply energy conservation. At the start the cart has only gravitational potential energy given by mgh where m is its mass, g is the gravitational field, h = 8m is the height. At the end the cart has on...

A coulomb the amount of charge that passes in 1 second when the current is 1 ampere.Q = It t = 5 x 60 = 300 (s) we must use Si units in physics hence the conversion to seconds here. Q = 5 x 300 Q = 1500 (...
