Energy Transfers and Transformations
Energy cannot be created or destroyed, meaning that the total amount of energy in the universe has always been and will always be constant. However, this does not mean that energy is immutable; it can change form and even transfer between objects.
A common example of energy transfer that we see in everyday life is the transfer of kinetic energy—the energy associated with motion—from one moving object to a stationary object via work.
In physics, work is a measure of energy transfer and refers to the force applied by an object over a distance. When a golf club is swung and hits a stationary golf ball, some of the club’s kinetic energy transfers to the ball as the club does “work” on the ball.
How does the energy of the sun reach earth?In an energy transfer such as this one, energy moves from one object to another, but stays in the same form. A kinetic energy transfer is easy to observe and understand, but other important transfers are not as easy to visualize.
Thermal energy has to do with the internal energy of a system due to its temperature.
When a substance is heated, its temperat
