Work Flashcards
1
Q
What is work conceptually?
A
Work appears when a force moves an object from one point to another. In other words, this is manifested when a force applied to something, moves that thing.
2
Q
Equation for work when the force is constant?
A
W = |F||d|cos(theta)
3
Q
Work with respect to dot product?
A
It is the integral of the dot product between the net force applied and the distance traveled.
4
Q
What is the S.I. Units for work?
A
Joules (as in energy)
5
Q
What is kinetic energy equal to and what is the relationship of this and work?
A
KE = (1/2)mv^2
W = Delta KE (change in kinetic energy)
6
Q
When is work positive or negative?
A
It is positive when the applied force is in the direction of the displacement and negative otherwise
