The SAT Subject Test in Physics assesses students' understanding of physics concepts and their ability to apply these concepts to solve problems.
Energy makes things happen! It can’t be created or destroyed—just transformed.
Work is done when a force moves something over a distance (\( W = Fd \)). If you push a box and it moves, you’ve done work!
Power tells us how quickly work is done (\( P = \frac{W}{t} \)). Lifting a heavy backpack quickly takes more power than lifting it slowly.
Understanding energy helps us design everything from roller coasters to wind turbines.
Climbing stairs increases your potential energy.
A car engine uses chemical energy to do work and make the car go.
Energy makes things happen, work is moving stuff with force, and power is how fast it happens.
