Hint:The inertia of motion is possessed by the man leaping from a moving bus. When the man falls on the ground, his feet quickly come to a stop, but his upper body continues to roll due to inertia of motion, causing him to slide forward.
Complete answer: To understand why jumping from a moving bus is dangerous, we must first understand inertia. Newton's First Law of Motion states that if a body is in motion, it will continue to travel at the same speed and in the same direction until an external force is applied to change its state.
Inertia is the resistance of some physical force to a shift in velocity, to put it another way.Changes in the speed or direction of motion of the object are included. One example of this property is objects' proclivity to continue travelling in a straight line at a constant speed even though no forces act on them.
As a result, jumping from a moving bus is dangerous since the jumping guy, who is moving at the bus's high speed, will appear to stay in motion due to inertia even after falling to the ground, and will be injured due to the ground's resistance.
Note:The question then becomes, how can one reduce the risk of falling when stepping down from a moving bus? As a result, the jumping guy, who is travelling at the same high speed as the moving vehicle, will reduce the risk by running alongside the moving bus and in the same direction as the bus.
