Physics equation flashcards
1
Q
a = f/m or f = m*a
A
f = resultant force m = mass a = acceleration
2
Q
a = v-u/t
A
a = acceleration v = final velocity u = initial velocity t = time taken
3
Q
w = m*g
A
w = weight m = mass g = gravitational field strength
4
Q
F=k*e
A
F = force K = springconstant E = extension
5
Q
W = f×d
A
W = work done F = force applied D = distance moved in the direction of the force
6
Q
P = e\t
A
P = power E = energy transferred T = time taken
