3.2 Forces Flashcards
1
Q
1 Newton
A
The force required to accelerate a mass of 1 Kg by 1 ms-2 in the direction of the force
2
Q
f = ma
A
force = mass x acceleration
3
Q
w = mg
A
weight = mass x gravittatoonal field strength
4
Q
Torque of couple
A
- One of the forces x perpendicular force between them
5
Q
p = m/v
A
density = mass/volume Kgm-3 = kg/m3
6
Q
p = f/a
A
Pressure = force/area
7
Q
Archimedes’ principle
A
The upthrust exerted on a body immersed in a fluid is equal to the weight of fluid that the body displaces
