formulas (1.3) Flashcards
1
Q
velocity formula
A
velocity = displacement / time taken
m/s = m / s
2
Q
momentum formula
A
momentum = mass x velocity
kgm/s = kg x m/s
3
Q
acceleration
A
acceleration = (final velocity - initial velocity) / time taken
m/s/s = (m/s - m/s) / s
4
Q
force
A
force = mass x acceleration
n= kg x m/s/s
5
Q
angular momentum
A
angular momentum = moment of inertia x angular velocity
kgm(2)r/s
6
Q
moment of inertia
A
moment of inertia = mass x distribution of mass from the axis of rotation
kgm(2)
7
Q
angular velocity
A
angular velocity = angular displacement/time taken
rad/sec
