Which one does not describe weight (three are true, pick the one that is false)? a. never changes b. is a force c. changes with g d. symbol is W

Work = force × a. work b. energy c. distance d. momentum

If the textbook weighs 19.6 newtons on venus,what is the strength of gravity on venus?

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].
