9.4 Elastic and inelastic collisions Flashcards
1
Q
What is an elastic collision?
A
» There is no loss of kinetic energy
» Momentum is conserved
2
Q
What is an inelastic collision?
A
» Where the colliding objects have less kinetic energy after the collision than before the collision
» Momentum is conserved
3
Q
Are objects that collide and couple together, inelastic or elastic collisions?
A
» Inelastic collision
» As some of the inital kinetic energy is transferred to the surroundings
4
Q
What is the equation to find the kinetic energy?
A
» E(k) = 1/2 x m x v^2
