The tutor tells another useful feature of the Sharp EL-520W: its built-in gravity constants.

Maybe you’re in high school physics, so you’re doing calculations related to gravity. You might be using the Earthbound formula F=mg, or the universal one, F=Gm₁m₂/r².

In the case of F=mg, you can call up g by pressing CNST 03 on the Sharp EL-520W.

For F=Gm₁m₂/r², you can call up G by keying CNST 02 on the Sharp EL-520W.

Good news, eh?

HTH:)
