The force exerted on a surface divided by the total area over which the force is exerted
What is Presssure
100
A system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area
What is Hydraulic system
100
The upward force exerted by a fluid on a summered object
What is buoyant force
100
The pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid
What is Bernoullis principle
200
Equal forces acting on an object in opposite direction (net force=0)
What is Balanced forces
200
The SI unit of pressure
What is Pascal
200
When force is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid
What is Pascals principle
200
The buoyant foce on an object is equal to the weight of the fluid displaced by the object
What is Archimedes principle
300
The tendency of an object to resist any change in its motion
What is Inertia
300
Air pressure decreases as elevation __________
What is Increases
300
Give example of hydraulic system
What is Star fish, brakes in car
300
The mass of a substance contained in a unit of volume
What is DENSITYYYY
400
The amount of matter in an object
What is MASS!!!
400

what is fluid
400
_________
__________
400
An object that is more dense than the fluid in which it is immersed ______ ( floats or sinks)
What is SINKS
500
NEWTONS LAW OF MOTION!!! :-)
an object at rest will remain at rest and an object moving at constant velocity will continue moving at constant velocity unless acted upon by an unbalanced force
