Forces Flashcards
1
Q
Equation for weight
A
W = m x gfs
Weight Mass. Gravitational field strength
2
Q
Equation for work done
A
W = F x s
Work done = force x distance
3
Q
Equation for force
A
F = K x e Force = spring constant x extension
4
Q
Equation for moment
A
M = F x D Moment = force x distance yeah
5
Q
Equations for pressure
x2
A
P = F / A Pressure = force / area
P = h x p x g Pressure = height x density x gravitational field strength
6
Q
Equation for distance travelled
A
S = v x t Distance = speed x time
7
Q
Equation for acceleration
A
A = V / t Acceleration = velocity/ time
8
Q
Equation for constant acceleration
A
v2 - u2 = 2a x s
Final velocity - initial velocity = acceleration
9
Q
Equation for resultant force
A
F = ma
F= resultant force M= mass A= acceleration
10
Q
Force
A
F= m^v \ ^t
M^v = change in momentum ^t = change in time
11
Q
Momentum
A
P = m x v
M= mass V= velocity
