Question

A bus is driving along a straight stretch of road. The bus driver named ray , has a cup of water resting on the dashboard. suddenly ray has to slam on the breaks Q: what is most likely to happen to the water in the cup

Answer 1

Water is most likely to spill from the cup.

•In the given conditions, when the bus driver will suddenly apply brakes, water will spill from the cup in the direction of the motion.

•This will happen due to the property of inertia of motion.

•Due to inertia of motion, water remains in the state of movement while bus and hence cup comes to rest. This causes water to remain moving and therefore spilling.

•The inertia of motion is defined as "the resistance of any physical object to any change in its state of motion" or it may also be defined as "the tendency of objects to keep moving in a straight line at a constant velocity."
