Formula

W = ฮ”KE = ยฝmvโ‚‚ยฒ - ยฝmvโ‚ยฒ

The net work done on an object equals its change in kinetic energy.

Worked Examples

Example 1: Accelerating object

Problem:10 kg, vโ‚=5 m/s, vโ‚‚=15 m/s

Solution:W=ยฝ(10)(225-25)=1000 J

Result:1000 J

Frequently Asked Questions

How does energy conservation work in physics?

The law of conservation of energy states that energy cannot be created or destroyed, only transformed. In a closed system, total energy remains constant. For example, a falling object converts potential energy (mgh) to kinetic energy (0.5mv^2). At any point, KE + PE = total mechanical energy.
