Newtons Laws Of Motion Flashcards
Newtons 3 laws
Basic classical laws describing motion
Newtons 1st law
Law of inertia, states that if the net force on an object is 0, an object at rest remains at rest and an object in motion remains in motion in a straight line with a constant velocity
Newtons 2nd law
States that the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass
F=ma
Newtons 3rd law
States that whenever one object exerts a force on a second object the second object always exerts a force on the first object which is equal in magnitude and opposite in direction
FBA =-FAB
Inertia
Tendency of an object to resist a change in its motion
Mass
A measure of the inertia on an object
Weight
The gravitational force on an object equal to the objects mass times the acceleration due to gravity
Force
A vector considered as a push or a pull, an action capable of giving rise to acceleration
Net force
Vector sum of all forces acting on an object
Force of frictiom
Force objects exert on each other when sliding past one another
Normal force
The force each object exerts on the other perpendicular to their contact surface
