measurement definitions Flashcards
1
Q
energy
A
capacity to do work, joules
2
Q
force
A
influence that tends to change the state of motion of an object, Newtons
Force = mass x acceleration
3
Q
joule
A
work done when force of one newton moves one meter in direction of force
4
Q
Newton
A
the force that will give a mass of one kg an acceleration of one meter per second per second, kg/m/s/s
5
Q
power
A
rate at which work is done, watts (joules/second)
6
Q
work
A
result of foce acting upon an object to cause its displacement in direction that force was applied, joules
work = force x distance
work = pressure x volume
7
Q
watt
A
1 watt is the power expended when 1 joule of energy is consumed in one second
8
Q
pressure
A
force applied over a unit area, pascals
pressure = force/area
