Conceptual Physics Chapter 6 Newton's Second Law of Motion

Force and Acceleration

Terms in this set (...)

Air Resistance
Friction acting on something moving through the air.
free-body Diagram
A diagram showing all the forces acting on an object.
The name for Liquids and gases, as they both flow.
Fluid Friction
When an object pushes aside the fluid it is moving through. (Like a Submarine through the water).
Means that two values change in opposite directions.
For Example: If an elevator goes up, the rope with weights on the other side goes down.
Newton's Second Law
Acceleration produced by a net force on an object is directly proportional to the magnitude of the net force, is in the same direction as that force, and is inversely proportional to the mass of the object.
Newton's 2nd Law
Basically, this means that Acc.~ net force/ mass
also, Acceleration= 1/mass and
acceleration= F(net force)
M (Mass)
The Amount of force per unit of area.
AKA P= (F) force/ (A) area of application
Measurement of pressure: is newtons per square meter
One newton per square meter is equal to one Pascals (Pa).
Terminal Speed
The speed at which an object which is falling has an acceleration of Zero, because friction balances out the weight.
Terminal Velocity
The terminal speed together with the direction of motion.
