instantaneous speed
measurement of how fast an object is moving at that particular moment.
net force
sum of all forces acting on an object
static friction
force that keeps an object at rest
first law of newton
an object will not change its motion unless a force acts on it.
second law of newton
the force on an object is equal to its mass times its acceleration
third law of newton
when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
projectile motion
motion of an object thrown in the air
centiripal force
a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
salts
substance produced by the reaction of an acid with a base
ionic bonds
1 or more metal from the periodic table
covalent bonds
dont have any metal elements
