What makes something float or sink?

Back 30

gravity pushes down
buoyancy pushes up

Front 31

Buoyancy

Back 31

the force of liquid pushing up against something- acts against gravity

Newton's 1st Law

Back 40

Object in Motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force- inertia

Front 41

Newton's Second Law

Back 41

F= ma
force= mass x acceleration

Back 44

faster in water than air
temperature affects it- travels faster at higher temperature

Front 45

Gravitation

Back 45

a natural phenomenon by which all objects attract each other- responsible for keeping the Earth and the other planets in their orbits around the Sun; for keeping the Moon in its orbit around the Earth; and for the formation of tides
