  • Front
  • Back
weight
a force determined by mass of an object times gravity w=mg
net force
the total sum of forces acting on a given object
pressure
the amount of force per unit area, measured in pascals (newtons per square meter
pascal
the unit of pressure = one newton per square meter
fluid
any material that flows
vector
can describe:
velocity
acceleration
force
displacement
motion
Pascal's principle
the idea that force in a fluid is transferable to all parts of that fluid
normal force
any force that acts perpendicular to the plane of motion
coeffficient of friction
the number associated with the interaction of two surfaces that determines frictional force
terminal speed
the maximum speed reached by a falling objecct slowed with air resistance (drag)
momentum
mass x velocity
impulse
the change in momentum of an object
law of conservation of momentum
in closed system (no net external forces) the momentum does not change
action force
the force of an object as it makes contact with another (initiating force)
newton's 3rd law
the law that describes the effect of different object on eachother in terms of force (for every action there is n equal and opposite reaction)
Newton's 2nd law
the acceleration produced by a net for on an object is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object
newton's 1st law
every object continues in a state of rest, or of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted upon it
