1.) if you are sitting still are you accelerating? how do you know? 2.) you’re on a skateboard, moving very fast but at a constant speed. are you accelerating? 3.) lara claims that if an object is accelerating it must be moving. she also claims that if an object is not accelerating it must be at rest. is she correct? if not, what would you say to prove her wrong?

yes. gravity is working on you and everything on you.

also earth is rotating

no not in respect ofimmediate surroundings

object could move at constant velocity = no change in either magnitude or direction

change of position "proves" this

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
