Lift an apple one metre
Lifting an apple one metre is the work needed to raise a small object against Earth's gravity over that distance.
How big is it?
1.765 J of energy
Energy · defined energy model
A little perspective
About 5.88 times the energy emitted in 60 seconds of Single-mode laser pointer optical output.
Single-mode laser pointer optical output: Single-mode laser pointer optical output is the continuous visible light power emitted by a standard handheld laser pointer operating in a single spatial mode.
Measurements, assumptions & sources +
Lift an apple one metre
Work against gravity for a 180 g apple raised 1 m, using 9.80665 m/s² and rounding.
Defined examples — our methodology
The marked energy is calibrated. Unmeasured illustration details are representative.
Single-mode laser pointer optical output
A defined 5 mW visible laser pointer output. The 0.3 J comparison is power multiplied by 60 seconds; beam class, wavelength and actual output matter.

Why we use 1.765 J
For comparison, this page uses energy. This is labelled defined energy model: an explicit comparison model rather than a claim that every example has the same value.
