PHYS 2010 Chapter Notes - Chapter 3.7-4.4: Relative Velocity, Contact Force, Net Force
Document Summary
Relative velocity - when the velocities are along the same lines. Force - any push or pull on an object. Contact force - when an object that"s applying force on another object is in contact with it. Force of gravity - why objects fall. Newton"s first law of motion (also called the law of inertia) Every object continues in its state of rest, or of uniform velocity in a straight line, as long as no net force acts on it. Inertia - the tendency of an object to maintain its state of rest or of uniform velocity in a straight line. Inertial reference frames - frames of reference in which newton"s first law is true. Noninertial reference frames - frames of reference in which newton"s first law isn"t true. Mass - quantity of matter, a measure of the inertia.
