Terms in this set (18)
any push or pull of an object; a vector quantity measured in newtons. Unbalanced force changes an object's motion.
The vector sum of all forces that act on an object.
An arrow whose length represents the magnitude of a quantity and whose direction represents the direction of the quantity.
any quantity that has both magnitude and direction. (force, acceleration, velocity)
any quantity that is described only by magnitude, not direction. (mass, volume, time)
when the net force on something is zero. (A state where no physical changes occurs.)
For any body in mechanical equilibrium, the vector sum of the forces on it are zero- that is, ∑F=0.
Force that completely balances the weight of an object at rest.
Is the upward force action on a suspended object. (Stretching force).
Is the downward force caused by gravitational pull.
Objects at rest.
Objects moving at constant speed in a straight-line path.
Property of things to resist changes in motion
Newton's First law of motion
Every object stays at rest unless or in speed of a straight line unless acted by another object.
proceeds from nature using the 5 elements
pushing or pulling forces
the sum (net result) of 2 or more vectors
state of no change
