Force and Acceleration

Air Resistance

Friction acting on something moving through the air.

free-body Diagram

A diagram showing all the forces acting on an object.

Fluid

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).

Inversely

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.

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)

also, Acceleration= 1/mass and

acceleration= F(net force)

__________

M (Mass)

Pressure

The Amount of force per unit of area.

AKA P= (F) force/ (A) area of application

AKA P= (F) force/ (A) area of application

Pascal

Measurement of pressure: is newtons per square meter

One newton per square meter is equal to one Pascals (Pa).

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.
