Newton's first law (inertia)
$F_{n e t} = 0 \Rightarrow v = constant$
Linear momentum
$p = m v$
Newton's second law
$F = \frac{d p}{d t}$
Second law (constant mass)
$F_{n e t} = m a$
Newton's third law
$F_{A B} = - F_{B A}$
Impulse
$J = \int F d t = Δ p$
Weight
$W = m g$
Contact force between two blocks
$f_{1} = \frac{m _{2} F}{m _{1} + m _{2}}$
F applied on m1
Tension in a massive rope
$T = F (1 - \frac{x}{L})$
Atwood machine acceleration
$a = \frac{( m _{1} - m _{2} ) g}{m _{1} + m _{2}}$
Atwood machine tension
$T = \frac{2 m _{1} m _{2} g}{m _{1} + m _{2}}$
Force on pulley (Atwood)
$R = 2 T = \frac{4 m _{1} m _{2} g}{m _{1} + m _{2}}$
Spring force (Hooke's law)
$F = - k x$
Spring cut in ratio
$k_{1} = \frac{( m + n ) k}{m}, k_{2} = \frac{( m + n ) k}{n}$
cut in ratio m:n
Springs in series
$\frac{1}{k _{e q}} = \frac{1}{k _{1}} + \frac{1}{k _{2}}$
Springs in parallel
$k_{e q} = k_{1} + k_{2} + \dots$
Apparent weight in a lift (up)
$W^{'} = m (g + a)$
Apparent weight in a lift (down)
$W^{'} = m (g - a)$
Weightlessness (free fall)
$a = g \Rightarrow W^{'} = 0$
Wedge constraint
$V_{3} = V_{1} sin θ$
velocities ⟂ contact equal
Newton's law for a system
$F_{e x t} = \sum m_{i} a_{i}$
Pseudo force
$F_{p se u d o} = - m a_{f r am e}$
Non-inertial frame law
$F_{r e a l} + F_{p se u d o} = m a$
Static friction range
$0 \leq f_{s} \leq μ_{s} N$
Limiting friction
$f_{s, m a x} = μ_{s} N$
Kinetic friction
$f_{k} = μ_{k} N$
Angle of friction
$tan ϕ = μ_{s}$
Contact force (max)
$F_{co n t a c t} = m g 1 + μ_{s}^{2}$
Angle of repose
$tan θ_{c} = μ_{s}$
Block on rough incline (about to slide)
$m g sin θ = μ_{s} m g cos θ$
Acceleration down rough incline
$a = g (sin θ - μ_{k} cos θ)$
Minimum force to move a block
$F_{m i n} = \frac{μ m g}{1 + μ ^{2}}$
pulled at optimum angle
