ENER

Conservation of mechanical energy states that the sum of kinetic (motion) energy and potential (position) energy remains constant in an isolated, conservative system.

Etotal=12mv2+mghE_{total} = \frac{1}{2}mv^2 + mgh

Whiteboard Solver Steps

Step 1

Total Mechanical Energy (Conservative)

At the starting peak, kinetic energy is zero (v=0v = 0), so the total mechanical energy is entirely gravitational potential energy.

Etotal=PEmax=mghinitial=78.4 JE_{total} = PE_{max} = mgh_{initial} = 78.4 \text{ J}
Step 2

Energy Inter-conversion

As the object slides down the curve, potential energy decreases and converts into kinetic energy. When climbing back up, the reverse happens, but total energy remains constant.

Etotal=KE(x)+PE(x)=12mv2+mgh(x)E_{total} = KE(x) + PE(x) = \frac{1}{2}mv^2 + mgh(x)
