Energy changes in object projected upwards
WebA system is an object or group of objects. There are changes in the way energy is stored when a system changes. For example: • an object projected upwards • a moving object hitting an obstacle • an object accelerated by a constant force • a vehicle slowing down • bringing water to a boil in an electric kettle Web2. Describe 5 examples which demonstrate how the way energy is stored changes when a system changes. An object projected upwards, a moving object hitting an obstacle, an object accelerated by a constant force, a vehicle slowing down and bringing water to the boil in an electric heater. 3. Name eight energy stores. Kinetic, electrostatic ...

The velocity as the rock reaches the ground will be greater than the initial velocity. Just try substituting values to test this out. v_f = v_i + at v_f = 15m/s - 5m/s^2 (10s) v_f = 15m/s - 50m/s v_f = -35m/s speed_f = v_f fryst cheesecake med pepparkaksbottenWebWhenever there is a change in a system, energy is transferred and some of that energy is dissipated.
