Question
In general, the work done by a force F is written as W=fiF (r )dr . Now, consider whether the following statements are true or false: The dot product assures that the integrand is always nonnegative. The dot product indicates that only the component of the force perpendicular to the path contributes to the integral. The dot product indicates that only the component of the force parallel to the path contributes to the integral. Enter t for true or f for false for each statement. Separate your responses with commas (e.g., t,f,t).
Explanation / Answer
a) The dot product assures that the integrand is always nonnegative False
b) The dot product indicates that only the component of the force perpendicular to the path contributes to the integral
= false
c) The dot product indicates that only the component of the force parallel to the path contributes to the integral true
(f,f,t)
