3.5 Flashcards
1
Q
conservation of linear momentum
A
the total linear momentum of a system is constant providing no external forces act
2
Q
impulse
A
rate of change of momentum (F delta t|)
3
Q
elastic collision
A
momentum and ke are conserved
4
Q
inelastic collision
A
momentum is conserved but ke is transferred into other forms
5
Q
newtons first
A
when a body is at rest or traveling at a constant velocity it will continue to do so unless an external force acts upon it
6
Q
Newtons second
A
the resultant force on a body is proportion to its rate of change of momentum
7
Q
newtons third
A
when a body exerts a force on an other body the second body exerts an equal and opposite force of the same type
