Question

What statement best defines work?

A.) work is the time it takes to move an object once acted upon by a force.
B.) work occurs when balanced forces act on an object and cause movement in the direction of these forces
C.) work occurs when a force causes motion of an object, and this motion is in the same direction of the applied force.
D.) work is the distance over time that an object moves once acted upon by a force.

Answer 1

I think the answer is C

Answer 2

The correct answer is C.
W=force into distance.

Option B states that "balanced forces act on on object and cause movement in direction of these force" which is against the laws of physics.
Option A is wrong because work is the product of force into distance,its not time.
Option D says that work is distance over time,which is wrong as:
speed=distance/time
So your left with option C
