Ch. 10 Forces Review

Force A push or pull
Newtons The units force is measured in
Friction A force that opposes motion
Balanced Forces Sum of the forces is zero.
Unbalanced Forces Always produce a change in motion
Newton's First Law An object at rest(or in motion) will stay at rest (or in motion) unless acted on by an unbalanced force
Inertia Objects resist any changes in their motion
Mass Measured in grams (or kilograms). Mass doesn't change.
Weight Pull of gravity. Measured in Newtons. Changes depending on your location.
Newton's Second Law Force = Mass(Acceleration) F = M(A)
Newton's Third Law For every action, there's an equal and opposite reaction.
Ways To Reduce Friction ball bearings, lubricants, sanding surfaces
Static Friction Friction between two objects that are touching but not moving. Takes the most force to overcome.
Sliding Friction Friction between two objects that are sliding against each other.
Rolling Friction Friction that occurs when one surfaces rolls over another.
Fluid Friction Occurs when an object moves through a fluid like air or water.
Gravity Depends on masses of objects attracted to each other and how far away they are from each other.
