Aristotle
Philosopher- scientist who stated theory of natural motion (movement up/ down) and violent motion(push/pull) and circular (earth orbit)
Copernicus
Astronomer who stated sun was center of universe- earth travelled around sun
Galileo
He discovered what we now call Newton's first law of motion. If friction is absent no force needed to keep object moving. Friction is important!!!
Friction
A force that opposes the motion of objects that touch as they move past each other
Inertia
Resistance of an object to a change in its motion
Newton's first law of motion ( inertia)
An essential law of motion that states every object continues in state of rest unless acted upon by force
No friction
Object in force-free environment will move forever
Mass and inertia
More mass more inertia
Mass
A measure of how much matter is in an object- property within
Kilogram
1000 grams measure of mass = 10 Newtons
Weight
Gravity reacting with mass as a force measured on earth in pds.
Newton ( measurement)
Measure of force
10 newtons
Equal to one kilogram= 2.2 pds
formula for mas to newtons: 13 kg. to ----?
13x10=130 N
Formula for newtons to mass 50N=.?? Kg
50/10= 5 kg.
