Question

Work is a _____________; a + or - sign on a work value indicates information about __________.a. vector; b. whether the work adds or removes energy from the object vector, c. the direction of the work vector scalar; d. the direction of the work vector scalar; e. whether the work adds or removes energy from the object

Answer 1

Work is a scalar; a + or - sign on a work value indicates information about the direction of the work vector scalar

Answer: Option D

Step-by-step explanation:

The measure of work done (W) on an objects by a given force can be determined to utilize the equation,

`W = F * d * \cos \theta`

Where, F represents the force and d is the separation over which the force demonstrations and theta is the point among F and d. Recognize that the angle remembered for the condition isn't only any old angles; it has a particular definition that must be recalled when taking care of such problematic. Work is a scalar quantity not a vector quantity. It does not depend on the direction as a vector depends.

Answer 2

The answer is: e. scalar; whether the work adds or removes energy from the object

Step-by-step explanation:

The work can be calculated with the following formula:

W = Fs

As you can see from the formula, work is a scalar product made up of two vectors, force (F) and displacement (s), therefore work can be said to be a scalar quantity.
