Chapter 4 - Newton's First Law of Motion - Inertia
Terms in this set (13)
in general, a state of balance. Examples:The state of a body on which no net force acts.
any influence that tends to acelerate an object; a push or pull; measured in newtons. A vector quantity.
the force that acts to resist the relative motion (or attempted motion) of objects or materials that are in contact.
the reluctance of any body to change its state of motion. Mass is the measure of inertia.
the fundamental SI unit of mass. One kilogram (symbol kg) is the amount of mass in one liter of water at 4 degrees C.
law of inertia
every body continues in its state of rest, or of motion in a straight line at constant speed, unless it is compelled to change that state by a net force exerted upon it. Also known as Newton's first law.
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 on its location (as weight does).
the combination of all the forces that act on an object.
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.
Newton's first law
every body continues in its state of rest, or of motion in a straight line at constant speed unless it is compelled to change that state by a net force exerted upon it.
for an object resting on a horizontal surface, the upward force that balances the weight of the object; also called the support force.
force that completely balances the weight of an object at rest.
the force on a body due to the gravitational attraction of another body (commonly the earth).
