Pro Tip

The work-energy theorem is powerful: to find an object's speed after being pushed, calculate the net work done on it, set equal to ΔKE = ½mv² − ½mv₀², and solve for v.

Did you know?

Carrying a heavy box across a flat room does zero work in the physics sense — the force (up) is perpendicular to displacement (horizontal), so cos(90°) = 0. Your muscles tire from holding the box, but no mechanical work is done on the box.
