Formula Flashcards
1
Q
W = m x g
A
Weight = mass x gravity
2
Q
W = F x s
A
Work done = Force x distance travelled
3
Q
F = k x e
A
Force applied to spring = spring constant x extension
4
Q
M = F x d
A
Momentum = Force x distance
5
Q
p = F / A
A
pressure = Force / Area of surface
6
Q
s = v x t
A
distance travelled = speed x time
7
Q
a = Δv / t
A
acceleration = change in velocity / time
8
Q
F = m x a
A
Resultant force = mass x acceleration
9
Q
p = m x v
A
momentum = mass x velocity
10
Q
Ek = 1/2 x m x v2
A
kinetic energy = 0.5 x mass x velocity squared
11
Q

A
Gravitational potential energy = mass x gravity x height
12
Q
P = E / t
A
Power = Energy / time
13
Q
P = W / t
A
Power = Work Done / time
14
