Just a short quiz tomorrow - Here is some concepts to review
A force is a push or pull that could cause movement. We studied 6 different forces:
o Gravity – A downward pull caused by the earth. It makes all objects fall at the same speed.
o Buoyancy – An upward push of a liquid or gas.
o Friction – The rubbing of two objects.
o Muscular Force – When humans or animals cause movement. It does not have the same affect on all
o Static Electric – Occurs when there are charges in an object. Opposite charges attract, like charges repel.
o Magnetism – Occurs when poles are aligned. Opposite poles attract, similar poles repel.
