Dynamics + Forces Flashcards
1
Q
N3L
A
when body A exerts a force on body B, body B exerts on body A a force of same type, equal in magnitude & opposite in direction
2
Q
N1L
A
an object stays at rest or continues to move at constant velocity unless a resultant force acts on it
3
Q
N2L
A
rate of change of momentum of a body is directly proportional to resultant force acting on it and takes place in direction of resultant force
4
Q
Hooke’s Law
A
extension/compression of spring is directly proportional to force applied on it provided limit of proportionality is not exceeded
