5A.1 energy in collisions Flashcards
what is elastic collision
a collision in which the total Ke is conserved
whats perfectly elastic, and an example of it
a tiny amount of energy is lost due to heat and sound example is noncontact forces (alpha particles being scattered by a nucleus)
what is inelastic collision
a collision in which the total Ke is not conserved
what are nonrelativistic speeds
speed much slower than the speed of light
how can you combine Ek+1/2v^2 and p=mv to get Ek in terms of p and m, and what is it used for
page 5, and it is used to find out the Ke of subatomic particles traveling at non-relativistic speeds
what is the large hadron collider expirement, and whst is it used for
it is an expereminet where alot of particles interactions ooccur and its used to find the mass of an unkonown particle by colliding it with a particle of known mass (using conservation of momentum)
