Newton's First Law of Inertia
Terms in this set (10)
A force is a push or a pull, and is a vector quantity. The metric unit of force is the Newton (N), the English unit of force is the pound (lb).
The combination of all the forces acting on an object. A net force on an object changes its motion.
Normal (Support) Force
The upward force that balances the weight of an object on a surface.
The force that acts between materials that touch as they move past each other.
The property of a body to resist changes to its state of motion.
Newton's First Law
A body at rest stays at rest, or of uniform speed in a straight line, unless acted on by a nonzero net force. (Sometimes called the Law of Inertia) (Things tend to keep doing what they're already doing unless a force acts on them!)
A state where the sum of the forces acting on an object is equal to zero.
The metric measure of mass. (1000 grams = 1 kilogram)
The quantity of matter in an object. The measure of the inertia, or "laziness" an object to a change in its state of motion.
The force of gravity on an object.
Calculate weight using the formula: w = m∙g
(weight = mass x acceleration due to gravity)
