Systems in Action Flashcards
Mass
amount of matter in an object
Weight
determined by the amount of gravity on an object
Work
The ability to move and object a distance
Mechanical System
group of physical parts that work together to complete a task
Gravity
force of attraction that draws 2 objects together because of their mass
Action-at-a-Distance Force
force that can push or pull an object without touching it
Energy
the ability to do work
Formula to find -Work in Joules-
Work in Joules=Force in Newtons
x
Distance in Meters
Formula to find Force of Gravity
Force of Gravity=Mass of object
x
the strength of
earths gravitational field
Formula to find Weight
Weight= kg x earths gravitational field (9.8)
Friction
action of one surface or object rubbing against each other
Systems
Systems come in al shapes and sizes
Mechanical Advantage
amount by which a machine can multiply an input force; determined by the ratio of the output force to the input force
