Gravitational Potential Energy is the work done in moving a mass from infinity to a point in a gravitational field. On the other hand, Gravitational Field Strength is the force exerted per unit mass on a ...

Max Gravitational Potential energy of combined mass:GPE = m x g x h= ( 0.0088 kg + 0.450 kg ) x 9.81 ms^-2 x 0.63 m = 2.84 J
Therefore Kinetic energy of the combined mass at the collision = 2.84 JKE ...

During a crash the velocity of the car is reduced to zero. The deceleration of the car exerts a force on the driver causing injury. Without a crumple zone the change in velocity is instantaneous therefore...

Region which a force acts on a charged particle and the force is same at all points.

Electricity is the flow of electrons through a material. But for electrons to pass through a material they have to give up some energy, this is called a material's resistance. The energy that is lost from...
