Terms in this set (...)

Philosopher- scientist who stated theory of natural motion (movement up/ down) and violent motion(push/pull) and circular (earth orbit)
Astronomer who stated sun was center of universe- earth travelled around sun
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!!!
A force that opposes the motion of objects that touch as they move past each other
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
A measure of how much matter is in an object- property within
1000 grams measure of mass = 10 Newtons
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.
