The kinetic energy of the ball is determined by the observer who considers herself stationary, and sees the ball moving with velocityVf. The kinetic energy is equal to the maximum amount of work that the ball could do if it were to strike its target and be left standing still, relative ...

2) The increase in internal energy between the block and the surface as a result of friction can be calculated using the equation W = µNΔx, where µ is the coefficient of friction, N is the normal force, and Δx is the distance the block moves. The normal force is equal to th...
After falling the distanceH, the kinetic energy equals the potential energy of Mass of the ball times the acceleration due to gravity times the height,H. So, KE = (Mb x V^2)/2 = Mb x g x H See? The Kinetic Energy at the end of the trip, is exactly equal to the Potential Ener...
All of these have equal potential energy. Correct Answer A. A truck at the top of a hill. ExplanationA truck at the top of a hill has the most potential energy because potential energy is directly related to the height of an object. The higher an object is, the more potential energy...
Potential energy and kinetic energy can interconverted and the sum of both quantities is equal to the total energy in a system. Potential energy is... Learn more about this topic: Energy | Definition, Types & Forms from Chapter 50/ Lesson 2 ...
