Friction
The force that acts to resist the relative motion (or attempted motion) of objects or materials that are in contact.
Inertia
The property of any body to resist changes in its state of motion. Mass is the measure of inertia.
Newton's First Law
Every body continues in its state of rest, or of motion in a straight line at constant speed, unless acted upon by a nonzero force.
Law of Inertia
Every body continues in its state of rest, or of motion in a straight line at constant speed, unless acted upon by a nonzero force.
Kilograms
The fundamental SI unit of mass. One kilogram is the amount of mass in one liter of water at 4 degrees Celcius.
Mass
A measure of an object's inertia; also a measure of the amount of matter in an object. Depends only on the amount of and kind of particles that compose an object - not its location.
Weight
The force on a body due to the gravitational attraction of another body.
Newton
SI unit of force. One newton (N) is the force applied to a one-kilogram mass that will produce an acceleration of one meter per second per second.
