Question

When two 10 lb forces act on the same object at the same time, what is their combined force?

a) 10 lb
b) 20 lb
c) 30 lb
d) 40 lb

Answer 1

Two 10 lb forces acting on the same object in the same direction combine to give a resultant force of 20 lb.

Step-by-step explanation:

When two 10 lb forces act on the same object at the same time, the combined force depends on the direction of the forces. If the forces act in the same direction, they add up to give a resultant force. In this case, if both 10 lb forces act in the same direction, their combined force is 20 lb. If the forces act in opposite directions, they would cancel each other out, resulting in no net force.
