Equations Flashcards
1
Q
F = M x A
A
F = resultant force M = mass V = velocity
2
Q
KE = 1/2 x M x V2
A
Ke = kinetic energy M = mass V = speed
3
Q
P = M x V
A
P = Momentum M = mass V = velocity
4
Q
W = F x D
A
W = work done F = force applied D= distance moved in direction of force
5
Q
P = E / T
A
P = power E = energy transferred T = time taken
6
Q
Efficiency = useful energy out % useful energy in (x 100%)
A
Efficiency = useful energy out % useful energy in (x 100%)
7
Q
W = M x G
A
W = weight M = mass G = gravity
8
Q
GPE = Mx G x H
A
GPE = Change in gravitational potential M = Mass G = gravitational field strength H = change in height
9
Q
S = d/t
A
S = speed D = distance T = time
10
Q
A = v - u / t
A
A = acceleration V = Final Velocity U = Initial Velocity T = Time Taken
