Forces Flashcards
1
Q
weight
A
weight = mass x gravitational field strength
W = mg
2
Q
work done
A
work done = force x distance
W = Fs
3
Q
force
A
force = spring constant x extension
F = ke
4
Q
elastic potential energy
A
elastic potential energy = 1/2 x spring constant x extension^2
Ee = 1/2 ke^2
5
Q
distance
A
distance = speed x time
s = vt
6
Q
acceleration
A
acceleration = change in velocity / time
a = Δv / t
7
Q
force
A
force = mass x acceleration
F = ma
8
Q
momentum
A
momentum = mass x velocity
