LAB 1 Quiz Flashcards
1
Q
mass
A
- quantity of matter an object contains
- a direct measure of the object’s inertia
- mass=weight/acceleration of gravity
2
Q
force
A
mass(kg) x acceleration (m/sec)
-measured in newtons (N)
3
Q
work (definition)
A
application of force through a distance
work=force(N) x distance (m) = Nm or 1 joule (J)
4
Q
power (definition)
A
rate at which work is performed
power=work (Nm)/time (sec) = Watts (W)
5
Q
ergometry (definition)
A
a measure of work (e.g. treadmill, cycle, swimming)
6
Q
units of measure
A
length: metre (m)
time: seconds (s)
weight: kilograms (Kg)
force: newton (N)
work: joule (J)
power: watt (W)
volume: litre (L)
7
