Generally it's false. The energy -state- of the object will change, but it may lose energy. If a car is 'pushed' to a higher speed, the force accelerating it does work on the car and the car gains kinetic energy. But if the brakes are applied, a force in the direction opposite the cars motion makes the car go slower. Work has been done (a force has been applied through a distance), but the kinetic energy of the car has been reduced.
DougTrue or false: when work is done on an object, the object gains energy?
Yes since work is only done in the y component that means that there was a shift from one heigth to another so that means there was a change in potential energy.
a change in potential energy equals the work exerted on an object.True or false: when work is done on an object, the object gains energy?
What if the work I'm doing is removing the battery?
This is true if there are no other forces on the object.
Pushing a crate across the floor does not add energy to the crate because it all goes to friction.
