Forces and Weight

Question	Answer
All falling object experience two forces:	A downward force, called Weight (N) An upward frictional forces, (E.G air reistance or drag through a fluid (R)
The faster an object moves through a fluid...	... the greater the fictional forces that acts upon it.
Gravity is the same everywhere.	FALSE Gravity varies where you are, in space there is no gravity.
Weight of an object is...	... the force exerted on its mass by the gravitational field strength (gravity).
The unit of Weight is...	... Newtons (N)
Gravity on Earth is...	... 10 N/kg, the unit for the strength of gravity is N/kg.
The Formula for calculating Weight is...	Image: 8a9cb512-1a85-4e65-9a7b-bfa59f79e0a6 (image/png)
John has a mass of 86.3 kg, what is John's Weight? The GFS of Earth is 10 N/kg	W = m x g m = 86.3 kg g = 10 N/kg W = 86.3 kg x 10 N/kg = 863 N
