Document Summary
Magnitude of gravitational acceleration near the surface of the earth. Value = 1000 kg/m3 = 1 g/cm3. Instantaneous velocity = speed and direction at a given moment. Average velocity = v = delta s/delta t. Average acceleration = a = delta v/delta t. Area under the curve for v vs t graph. An object in motion tends to stay in motion. An object at rest tends to stay at rest. Velocity will only change with an applied net force. Measure of an object"s resistance to acceleration (inertia) Applied net force causes a change in motion. Fnet and a point in the same direction. If fnet= 0, then a = 0, and vice versa. Velocity is constant, but not necessarily zero. Points along the rope, away from the object. Exerted by a surface to keep itself intact. Forces can only be applied through contract, with the exceptions of. For every action there is an equal and opposite reaction.
