Contact ForceA as long as ce that can cause or change motion of an object by touching it. Motors in addition to gears operate through contact as long as ces. Non-Contact ForceForce that results when the two objects are not in physical contact with each other, yet are able to exert a push or pull. Force: A push or PullContact Force Examples: FrictionNormal ForceAir ResistanceApplied ForceNon-Contact Force Examples: Gravitational ForceElectrical ForceMagnetic ForceApplied Force: A as long as ce typical push or pull, pushing a door open, pulling a rope. Friction: Happens when two objects rub against each other. Friction opposes motion. Normal Force: The normal as long as ce is the support as long as ce exerted upon an object that is in contact with another stable object. For example, if a book is resting upon a surface, then the surface is exerting an upward as long as ce upon the book in order to support the weight of the book.Air Resistance: The air resistance is a type of frictional as long as ce that acts upon objects as they travel through the air. Contact ForcesContact ForcesNormal Force= 10N

Magnetic Force: A kind of non contact as long as ce, materials such as iron, nickel, cobalt in addition to other magnets just need to be near the magnet to be attracted or repelled.Electric Force: Noncontact as long as ce of electrical charges.Gravitational Force: The as long as ce of attraction between any two objects in the universe. All objects have gravitational as long as ce. The mass of an object in addition to its distance determines the strength of its gravitational as long as ce. NON-Contact ForcesGravityMass in addition to distance affect the as long as ce of gravity. The greater the mass in addition to the closer the object, the stronger its gravitational pull. GravityThe as long as ce of gravity between two objects depends on two factors: MassDistanceLonger arrows represent a greater as long as ce of gravity.How does the as long as ce of gravity change as the mass of objects in addition to distance between them changes

The amount of matter in an object.Unit: GramsDoes not depend of gravity. Measured with a triple beam or digital balance. Measure of the Earths gravitational pull (a as long as ce).measured in lbs. or NChanges depending on the gravitational as long as ce. Measured using a spring scale.
