Proportional to velocity and mass p=mv Two things to remember about momentum 1: conserved in an isolated system 2: it is a vector How to solve elastic collision vs inelastic collision problems Elastic: use conservation of energy Inelastic: (in an isolated system) use p(initial)=p(final) Define impulse and give equation Impulse (J): IAS equal to change in momentum J=Δp Equation for the average force on colliding bodies J=FavgΔt Equation to find average force from change in momentum Δmv=FavgΔ t Define a machine Machine: mechanical device which reduces force to do work. Work does not change Define radioactive decay Radioactive decay: spontaneous breaking apart of atoms Alpha decay (Z-2) and (a-4) Beta decay Creation of an electron and proton from a neutron. Election is expelled (Z+1) and (a+0) and (-e-1) Positron emission Expulsion of a positron when a proton becomes a neutron (Z-1) (a+0) (+e-1) Electron capture Capture electron and merge it with a proton to form a neutron (Z-1) (-e+1) (a-0) Define fusion and fission Fusion: cumbining two nuclei to form a heavier nucleus Fission: splitting a nucleus to form two lighter nuclei Automatically remove your image background.
