A child is on a playground they start to slide down a large slide. At what point is the child in dynamic equilibrium with the slide?
When the child pushes themselves down the slides.
When the child pushes themselves down the slides.
As the child is in motion as they are sliding down.
When the slide ends and the child has stopped moving .
The child will not reach dynamic equilibrium.
Which statement correctly defines%C2%A0dynamic equilibrium?
Dynamic equilibrium refers to a state in which the forces acting on an object are balanced, resulting in no net acceleration of the object. In the case of a child sliding down a large slide, dynamic equilibrium can occur when the forces acting on the child are balanced, causing the child to maintain a constant speed while sliding.
When the child pushes themselves down the slide, they exert a force in the downward direction. This force helps to overcome the force of friction between the child and the slide, allowing the child to start sliding. At this point, the forces are not yet balanced, and the child is not in dynamic equilibrium.
As the child continues sliding down, the force of gravity acts in the downward direction and the force of friction acts in the opposite direction, slowing down the child's slide. When these forces become equal and opposite, canceling each other out, the child reaches dynamic equilibrium. This means that the child is moving at a constant speed without accelerating.
However, it is important to note that the child will not remain in dynamic equilibrium until the slide ends and the child stops moving. As the child slides down, various factors like air resistance, changes in slope, and the child's body position can cause fluctuations in the forces acting on the child, leading to changes in speed. So, while there may be brief moments of dynamic equilibrium during the slide, it will not be a continuous state until the slide comes to an end.
