Chapter 11 lesson 2
Newtons law of universal gravitation
the plants,the stars,and all particles of matter exert gravitational force.
Newton's first law of motion + an object at rest tends to stay at rest unless something's moves it an object in motion tends to stay in motion unless something stops it
You left a book on the table over night and when you wake up it is still there
Newtons 2 law + acceleration depends on the objects mass and the amount of net force applied to it
A baseball hit with a bat flies farther than a bowling ball hit with a bat
Newtons 3 law + for every action force there is an equal and opposite reaction force
A balloon flies forward when air quickly escapes from it
weightlessness
it is wear you feel that you have no weight ex. going bungy jumping or jumping off a plan
