Dynamics, Force And Newtons Law Flashcards
1
Q
What is velocity?
A
Rate of change of position
v = delta x / delta t
2
Q
What is acceleration?
A
Rate of change of velocity
a = delta v / delta t
3
Q
What is momentum?
A
mass x velocity
4
Q
What is Newtons first law?
A
A body remains in a state of rest or uniform motion in a straight line unless it is acted upon by a force (Wd = F x delta x)
5
Q
What is Newtons second law?
A
The rate of change of momentum of a body is equal to the force applied (F=ma)
6
Q
What is Newtons third Law?
A
For every force acting on a body there is an equal and opposite reaction ( conservation of momentum in a closed system)
7
Q
What is density?
A
mass per unit volume of a substance.
p = m/v
