-- Take two rocks or two Bowling balls.
-- Find two buildings with different heights. Measure their heights.
-- Drop one rock or bowling ball from the roof of one building. Measure
the time it takes to hit the ground.
-- Drop another rock or bowling ball from the roof of the other building.
Measure the time it takes to hit the ground.
-- Now you have all the information you need to calculate the acceleration of gravity.

Wait a second! Stop the presses! Hold the back page!
I thought about it some more.
You only have to do one drop, and you have all the information you need
to calculate the acceleration of gravity.
The mass of an object that weighs 98 newtons can be calculated using the formula: weight = mass x acceleration due to gravity. If the acceleration due to gravity is approximately 9.81 m/s^2, then the mass of the object would be approximately 10 kilograms.
98 Newtons.
It is approx 98 newtons.
98 newtons is equivalent to approximately 22 pounds.
The same 10 kg weighs 16 newtons on the moon, 35.2 newtons on Mars, 98 newtons on earth, and zero newtons while in space coasting from any one of them to either other one.
A 10 kg box weighs a touch more than 98 newtons (98.0665002864).
On earth: 98 newtons (22.1 pounds) On the moon: 16 newtons (3.6 pounds)
98.07 newtons (Force = mass x acceleration)
(98/5271) x 100 = 1.859%
18kg converts to about 39.6 pounds @2.2lbs per kg
On earth, 10 kg of mass weighs roughly 98 newtons.
F = M A = (20) (10) = 200 newtons
