Question

example of static equilibrium in everyday life

Answer 1

example 1 = the car is in dynamic equilibrium because it is moving at constant velocity. There are horizontal and vertical forces, but the net external force in any direction is zero. The applied force between the tires and the road is balanced by air friction, and the weight of the car is supported by the normal forces, here shown to be equal for all four tires.

example 2:- An object in static equilibrium is one that has no acceleration in any direction. While there might be motion, such motion is constant.
