Answer:
The action-reaction pair of forces that exist between the aerialist and the tightrope can be explained by Newton's third law of motion. According to this law, for every action, there is an equal and opposite reaction. In the case of the aerialist walking on a tightrope, the action force is exerted by the aerialist on the tightrope, while the reaction force is exerted by the tightrope on the aerialist.
When the aerialist walks on the tightrope, they push down on the rope with their feet. This downward force creates an action force on the tightrope. As a result of Newton's third law, an equal and opposite reaction force is exerted by the tightrope on the aerialist. This reaction force allows the aerialist to maintain balance and prevents them from falling off the tightrope.
The balancing bar held by the aerialist also plays a crucial role in maintaining balance. By holding onto the bar, the aerialist can exert additional downward forces on different sides of their body. These downward forces create corresponding reaction forces from the tightrope, helping to stabilize and counteract any potential tilting or tipping motions.
It is important to note that while there are action-reaction pairs of forces between the aerialist and the tightrope, these forces do not cancel each other out completely. The action force exerted by the aerialist is greater than the reaction force exerted by the tightrope due to differences in mass and strength. This imbalance allows for controlled movements and adjustments by the aerialist to maintain balance.
In summary, when an aerialist walks on a tightrope and holds a balancing bar, there exists an action-reaction pair of forces between them and the tightrope. The action force is exerted by the aerialist on the tightrope, while the reaction force is exerted by the tightrope on the aerialist. These forces enable the aerialist to maintain balance and stability while performing their acrobatic feats.
