It can be (or, rather, result in) either. The “Work-Kinetic Energy” Theorem states that the NET work done on a PARTICLE (i.e., an object that has no “internal” way of storing energy) equals the change in KE. If only a single force acts, then the w.
Energy is another word for power. Energy makes things move. It makes machines work. Energy also makes living things grow.
Work. The concept of work in physics is much more narrowly defined than the common use of the word. Work is done on an object when an applied force moves it through a distance. In our everyday language, work is related to expenditure of muscular effort, but this is not the case in the language of physics. A person that holds a heavy object does no physical work because the force is not moving.
Homework, Chapter 6: Energy.. This work done on the bullet means its KE (kinetic energy) increases. If the distance over which the force acts increases,. Work done by the brakes changes the car's KE from its initial value to zero.
Kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
Thermal energy is used to cook food. Thermal energy is heat. It's converted from either electrical potential energy or chemical potential energy, depending on the cooking appliance.

Because there’s no movement, no work is done and you have no net increase in kinetic energy from the two forces. Take a look at the figure. You may want to determine the speed of the 100-kilogram refrigerator at the bottom of a 3.0-meter-long ramp, using the fact that the net work done on the refrigerator goes into its kinetic energy.
