_________ the measure of the force a gravitational field exerts on an object.
The _________ of an object depends on its mass, shape, and surface area; the _________of a feather of low mass and high surface area might be substantially less than 1 ft/s.
Air is a _________ fluid, it exerts force on a moving object, and when a person in free fall reaches a speed of about 180 ft/s (120 nules per hour), the air resistance force is equal to the force of gravity, and one stops accelerating. This is known as terminal velocity.
Force is that which changes the _________of an object.
_________ is a measure of the amount of material present in an object, that is, the quantity of matter. It is not influenced by gravitational fields, and an object s mass is constant whether on the earth s surface or in outer space.
