Forces and Energy

Review for Test on Tuesday

friction a force that shows objects down. It always acts in the opposite direction of motion.
gravity a force that pulls objects together
force a push or a pull
Newton (N) the unit of force
Isaac Newton The scientist that wrote the 3 Laws of Motion which described gravity and the laws of motion.
Balanced Forces equal forces in opposite directions (Net force = 0 (n)
unbalanced forces unequal forces in opposite directions (Net force > 0 (n)
rough surface a surface texture that creates more friction (ex: carpet)
smooth surface a surface texture that creates less friction
energy the ability to make something move
joule (J) the unit for energy
potential energy stored energy in objects at rest
kinetic energy energy in moving objects
the Law of Conservation of Energy Energy cannot be created or destroyed. It can only change form.
