A free-body diagram is drawn in order to find which quantity?
AThe elapsed time
BThe temperature
CThe net force
DThe total mass
Answer & Solution
Correct answer: C. The net force
1. The diagram serves a specific calculation.
2. Free-body diagrams visualise the forces exerted on a given object.
3. They are used in order to find the net force.
4. The net force then determines the object's motion.
