Measurements, assumptions & sources +
Tennis ball serve kinetic energy
Defined launch kinetic energy: 120 J; derived calculation; range 60 J–180 J.
A defined 120 J serve model, corresponding to a 57.7 g regulation tennis ball moving at about 64.5 m/s, using E = ½mv². Ball mass and launch speed determine the result.
The marked defined launch kinetic energy is calibrated. Unmeasured illustration details are representative.
Golf drive ball kinetic energy
Defined launch kinetic energy: 130 J; derived calculation; range 80 J–200 J.
A defined 130 J drive model, corresponding to a 45.93 g regulation golf ball moving at about 75.2 m/s, using E = ½mv². Ball mass and launch speed determine the result.
USGA and R&A — Equipment rules

Why this measurement?
Why we use 120 J
We compare the kinetic energy of a served tennis ball. This is calculated from stated inputs and assumptions, not a direct measurement. The recorded range is 60 J to 180 J.
A defined 120 J serve model, corresponding to a 57.7 g regulation tennis ball moving at about 64.5 m/s, using E = ½mv². Ball mass and launch speed determine the result.
