| 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... | |
| 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 |
