kinetic energy

KE=1/2mv^2

Conservation of mechanical en

applies only when the non-conservative forces do no net work

conservation of linear momentum

applies only when there is no net external forces

non-conservative forces

constraint forces (tension,normal force, and static friction), dissipative forces (kinetic friction and collisional forces)

if a completely elastic collision takes place, during the collision, what is conserved?

mechanical energy, momentum, and energy

if an inelastic collision takes place, during the collision, what is conserved?

momentum and energy

gravitational pote
