Question
Which of the following is always true for an object moving in a straight line at constant speed?
A. No forces act on the object.
B. No resultant force acts on the object.
C. The momentum of the object is zero.
D. No work is being done on the object.
Markscheme
B
Examiners report
No work is done only if there are no forces on the object. So clearly the only possible answer is B.
