Vocab 2 Flashcards
Interim
Motion Ina straight line unless that state is changed by an external force
Newton’s first law of motion
At rest and an object in motion stays in motion with the same speed and in same direction unless acted upon by an unbalanced force
Newton’s second law of motion
Same direction as the net force and inversely proportional to the mass of the object
Newtons 3rd law of motion
Pair of forces acting on the two interacting objects
Size of forces in the first object equals the 2nd object
Air resistance
Observed to oppose the motion of an object
Terminal velocity
Act upward and oppose the force of gravity
Free fall
Move under the force of gravity
Centripetal force
Acts on body moving in a circular path and is directed toward the center around which is moving
Law of conservation of momentum
Closed system remains constant through Time regardless of other possible changes within the system
