Initially, when you drop an object the only force acting on it is gravity. This accelerates the object towards the ground. As the objects speed increases so does the force of air resitance acting on the o...
Well it all depends on how the energy of the moving objects is transfered during the collision. In a elastic collision, first the objects are moving toward each other with both a certain kinetic energy, t...
How much electrical charge has been transferred per second (from the relationship Q=It) charge = current x time.
In order to answer this question, we need a formula which relates resistance to voltage and power. We don't already know this formula, but can create it from two formulae we already know: P=IV & V=IR....
