A-LEVEL PHYSICS: 11.1.7: Angular Impulse (SaveMyExams) Flashcards
1
Q
in linear motion, the resultant force of a body can be defined as the rate of change of ___ ___:
A
linear momentum (p)
F = ∆p/∆t
2
Q
linear impulse (∆p):
A
average resultant force (F) acting over change in time (∆t) to produce a change in linear momentum (∆p)
3
Q
resultant torque (τ) = …
A
τ = ∆L/∆t
resultant torque = change in angular momentum / change in time
4
Q
angular impulse (∆L) = …
A
∆L = τ∆t
5
Q
angular impulse describes the effect of a ___ acting over a…
A
torque, change in time
6
Q
small torque acting over a long time has the same effect as…
A
large torque acting over a short time
7
Q
area under τ-t graph:
A
angular impulse (∆L)
(∆L = τ∆t)
