Formulae Flashcards
1
Q
Formula to find acceleration, given time and change in velocity
A
a= triangle v/triangle t
2
Q
Formula to find acceleration, given net force and mass
A
a = Fnet/m
3
Q
Formula to find pressure, given force and area
A
P = F/A
4
Q
Formula to find force, given work and distance
A
F = W/d
5
Q
Use the formula Ep = mgtriangleh
Find Ep if m = 5kg, triangle h = 4m & 10 N kg-1
A
Ep = 5 x 10 x 4 = 200J
6
Q
Use the formula P = W/t
Find t if P = 50 and W = 1000J
A
t = W/P
t = 1000/50
t = 20
