Question
An acrobat is hanging upside down, motionless, on a swing far above a crowd.Determine whether the forces acting on the acrobat are balanced or unbalanced. Explain your answer.
Solution
The forces acting on the acrobat are balanced. Here's why:
-
The acrobat is motionless: This means that there is no net force acting on the acrobat, which is a characteristic of balanced forces.
-
Gravity is pulling the acrobat downwards: This is the force of gravity, which always acts downwards towards the center of the Earth.
-
The swing is exerting an equal force upwards: The swing (or more specifically, the tension in the ropes of the swing) is exerting an upward force on the acrobat. This force is equal in magnitude but opposite in direction to the force of gravity.
-
These forces cancel each other out: Because these two forces are equal and opposite, they cancel each other out. This results in a net force of zero, which means the forces are balanced.
Therefore, since the acrobat is not moving and the forces acting on him cancel each other out, we can conclude that the forces are balanced.
