1st week Flashcards
is any push or pull.
Force
Force that is applied on an object through direct pushing or pulling
Applied force
Force exerted by gravity; also known as weight; mass times gravity
Gravitational force
Force that is perpendicular to the surface an object is in contact with; if there’s no surface in contact, then there’s no normal force
Normal force
Force present in springs
Elastic force
Force that is present in cables, strings, cords, and other similar materials
Tension force
Force that impedes motion, two surfaces that contact and slide against eachother
Frictional force
what are Newton’s three laws of motion?
Inertia, Acceleration, Action and Reaction
An object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line.
1st Law: Inertia
states that it is directly proportional to the force and is inversely proportional to the mass.
Second Law: Acceleration
law states that for every action (force) in nature there is an equal and opposite reaction.
Third law: Action and Reaction
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
Third law: Action and Reaction
is the support force exerted upon object that is in contact with another stable object.
Normal Force
force that is transmitted through a string, rope, cable, or wire when it is pulled tight by forces, acting from opposite ends
Tension force
force that acts between surfaces that are in contact with another
friction force
