Review: Mass, Gravity and Weight
Q: Gandalf weight = 2.4 kg means [E]
‘weight’ has a different meaning in physics
Mass, Gravity & Weight
- Mass is an intrinsic property
oIt says how Newton’s Laws apply to that object
-Gravity: an attractive force that exists between any two objects that have a mass … FG
oUsed for objects close to Earth’s surface
Flat Earth approximation
oOften written as Fg
- Weight of an object is a measurement of force made by the floor on the object.
oYou can’t feel weight when you lose contact with any surface that’s pushing on
you
You are ‘weightless’ & only gravity is acting on you
Q: Maxwell mass = 5.3 kg, w=? [E]

Only happens when Maxwell is on
level surface & not doing anything
