1. What happens when two unbalanced forces act on an
object?
Consider a game of tug of war between Tim, Elena, and Anne. Tim can pull
with a force of 70 N, Elena can pull with a force of 100 N, and Anne can
pull with a force of 30 N. Determine if the different configurations of teams
are balanced or unbalanced. Write the configuration of teams in the correct
row.
Balanced
Unbalanced
• Tim versus Elena and Anne
• Elena versus Tim and Anne
• Anne versus Tim and Elena

Answer:

Explanation:

Equilibrium is the state in which the resultant of all forces acting on an object is zero. This implies that the object do not rotate or move, but well balanced at a point. Equilibrium can either be dynamic or static.

When two unbalanced forces act on an object, the object move in the direction of the greater force. This effect nullifies equilibrium of the object.

i. Tim versus Elena and Anne - Unbalanced balanced

⇒  70 - (100 + 30) = -60N

ii. Elena versus Tim and Anne - Balanced

⇒ 100 - (70 + 30) = 0N

iii. Anne versus Tim and Elena - Unbalanced

⇒ 30 - (70 + 100) = -140N
