calculating net force
net force =
directions: calculate the net forces acting on the objects described below. circle the number of
any problem that results in no motion.
1.
2.

Explanation:

Step1: Analyze the first case

For the first object, the forces are \(5N\) (downward) and \(5N\) (upward). Since they are equal and opposite (\(F_{net}=F_{1}-F_{2}\), where \(F_{1} = 5N\) (down) and \(F_{2}=5N\) (up)), \(F_{net}=5 - 5=0N\).

Step2: Analyze the second case

For the second object, the forces are \(5N\) (downward) and \(3N\) (downward). As they are in the same direction (\(F_{net}=F_{1}+F_{2}\), where \(F_{1} = 5N\) and \(F_{2}=3N\)), \(F_{net}=5 + 3=8N\) (downward).

Answer:

1. \(0N\)
2. \(8N\)
