momentum

Question 1

What is momentum

Answer 1

momentum is the product of mass x velocity

P = mv

Question 2

What are the two types of collisions

Answer 2

elasitc and inelastic

Question 3

Elastic collision:

Answer 3

where both momentum and kinetic energy are conserved

Question 4

Inelastic collision

Answer 4

where only momentum is conserved, while some of the kinetic energy is converted into other forms (e.g heat, sound, gravitational potential) and may be larger or smaller after a collision

Question 5

what do you need for a perfectly elastic collision

Answer 5

For a perfectly elastic collision, the relative speed of approach before the collision is equal to the relative speed of separation ofter the collision
