Which of these is a good example of newton's first law of inertia

a) a ball sits motionless on the ground

b) a ball gathers speed as it rolls downhill

c) a ball accelerates as it falls out of the classroom window

d) a ball slows down after it is kicked through the grass

A good Example of Newton's First Law of Inertia is actually A

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

i believe the answer is a
