Forces Flashcards
1
Q
Gravitational Force
A
F = mg
2
Q
Spring Force
A
F = -kx
3
Q
Newton’s Laws
A
1) Inertia, 2) F = ma = dp/dt, 3) Action-Reaction pairs
4
Q
Centripetal Force
A
F = m(v^2)/r
5
Q
Static Friction
A
F ≤ F_N x μ_s
6
Q
Normal Force
A
F_N, force in reaction to the contact between two surfaces
7
Q
Kinetic Friction
A
F = F_N x μ_k
8
Q
Coriolis Force
A
F = - 2 m (w x v) where x is the cross product,
F = - 2mwv sin(theta), where theta is the latitudinal angle
9
Q
Buoyant Force
A
F_B = pVg, p = density of the fluid, V = volume of fluid displaced, g = grav. acceleration
