Mechanics Facts (unlike A-level, you need to remember these)A moment is the force multiplied by the distance perpendicular from the line of action of the force to the pivot. Measured in 𝑁𝑚.
Moment=Fd
∑clockwise moment=∑anticlockwisemoment
Force not perpendicular?
Turns out that L is the shortest distance along line of force to the axis. So it turns out that:l=r sin θ
Moment of acouple=Fs
Motion: v= ΔsΔ t
a= ΔvΔt
suvat equations: v=u+at s=( u+v2 )t v2=u2+2as s=ut+ 12a t 2
Newton’s second law: ∑F=Δ(mv)Δ t
F=ma F Δ t=Δ(mv)
Momentum: Δ p=m Δv momentumbefore=momentumafter
Energy: W=Fscosθ Δ E p=mg Δh Ek=12mv2
Springs: F=k Δ L Ep=12F ΔL Ep=1
2k Δ L2
Springs in series: 1keq
= 1k 1
+ 1k2
Springs in parallel: k eq=k1+k2
Density: ρ=mV Density of an alloy: ρ=ρ1V1 + ρ2V2
V 1+V 2
