Gravity: the Laws of Motions
... • Weight is the force exterted by gravity on a massive body (body with mass), e.g. placed on the surface of Earth • Weight is a measure of the gravitational force exerted on that material. • Thus, mass is constant for an object, but weight depends on the location of the object. • Your mass is the sa ...

____The Force Table
... An object may be acted upon several forces at one time, each varying in magnitude and direction. Their combined effect on the object depends on both the magnitude and the direction of the forces. If two forces, equal in magnitude, act on the object in opposite directions, they will produce no change ...

Newton`s Laws
... Every object continues in its state of rest, or of motion in a straight line at constant speed, unless compelled to change that state by forces exerted on it. Also called Law of Inertia: things move according to their own inertia Things keep on doing what they are doing Examples: Hockey puck on ice, ...

An Investigation of a Model for Air Resistance
... Introduction: When an object falls near the Earth’s surface it experiences the force of gravity as well as a drag force due to air resistance. In first year physics, most students are told to “ignore” wind resistance. This lab is designed to show that a model equation may be tested. One of the simpl ...
