Webb7 okt. 2024 · efficiency = useful energy out ÷ total energy in (for a decimal efficiency) or. efficiency = (useful energy out ÷ total energy in) × 100 (for a percentage efficiency) How do you increase efficiency in physics? This can be achieved by reducing wasted energy transfers so more of the input energy is usefully transferred.
WebbJoin now. Step 1: Write down the efficiency equation. Step 2: Rearrange for the power input. Step 3: Calculate the power output. The power output is equal to energy ÷ time. The electric motor transferred electric energy into gravitational potential energy to lift the load.
