Question Answer
Power - UntsP=ΔE/Δt - W or J/s
Change in Ug - UnitsΔUg=Ug(f)-Ug(i) - J
GPE (Ug) - UnitsUg=(m)(g)(h) - J
Work (2 equations) - UnitsWork = Force*Distance or W=ΔK=K(f)-K(i) - J or N*m
Inelastic Collisions (energy) - UnitsK1(i)+K2(i)=K1(f)+K2(f)+ thermal or some other energy - J
Kinetic Collisions (energy) - UnitsK1(i)+K2(i)=K1(f)+K2(f) - J (always the same on both sides)
Kinetic energy - UnitsK=(1/2)(m)(v)^2 - J
Conservation of linear momentum - Unitsp(i)=p(f) - m/s
Conservation of linear momentum (inelastic collisions)p1(i)+p2(i)=p1(f)+p2(f)
Conservation of linear momentum (Perfect inelastic collisions)p1(i)+p2(i)=p(f)
Change of change of objects Momentum - UnitΣF=Δp/Δt - kg(m/s)
Change in momentum of an object - unitsI=Δp (more specifically _=p(f)-p(i)) - kg(m/s)
Impulse - UnitsI=F(net)*time
Linear momentum - Unitsp=(m)(v) - kg(m/s)
Law of Universal Gravitation - UnitsF(g)=(G)[(m(1)m(2))/((r)^2)] - m/s^2
