KINETICS - work, energy and power Flashcards
1
Q
a force can instantaneously produce what
A
linear and angular acceleration
2
Q
over time a force can produce what
A
linear and angular impulse
3
Q
what is work
A
the transfer of energy by a force, that causes an object to be displaced
4
Q
what type of quantity is work
A
scalar
-force and displacement need to be in same direction
5
Q
work can be quantified as what
A
the area under a force-displacement curve
-for constant and non-constant forces
6
Q
what is the riemann integration method
A
area under force time or disaplcement curve in square form
-area = F x d
7
Q
what is the trapezoidal integration method
A
area under force time or displacement curve in sections
- Wi = Fi x di
8
Q
A
