The _______________ of an object can be calculated using the equation: W = m x g. On Earth, this means the weight is 10 times the mass, as the Earth’s gravitational field _______________ is 10 N/kg. The faster a body moves through a fluid, the _______________ the frictional force on the object. A body falling through a fluid will _______________ at first because of its weight. This will increase the friction, so the resultant force will _______________ . It will continue to accelerate until it reaches a terminal velocity when the weight is balanced by the _______________ .
