Q

Divergent venturi tube

A

Decrease velocity and increase pressure

17
Q

Boyles Law

A

Increase pressure = decrease volume

Decrease pressure = increase volume

18
Q

Charles Law

A

Increase temperature = increase volume

decrease temp = decrease volume

19
Q

Newtons first law - law of inertia

A

A mass at will remain at rest or in motion until acted upon by an outside force

20
Q

Newtons 2nd law - law of force and acceleration

A

when a body is acted upon by a constant force, its aceleration is inversely proportional to its mass

21
Q

Newtons third law - law of interation

A

for every action, there is an equal and opposite reaction

22
Q

Heat

A

form of energy produced by motion of melecules known as kinetic energy

23
