Explain the outcome. The results did match my prediction of the most weight having the most momentum and the most energy out of the three. This is because the more mass you have the more energy and momentum you will have when you collide with a fixed object 2) Was momentum conserved?

Answer 1

Answer : --

• ok first of all we discuss about the basic deffinition & formulas
• elastic & inelastic collision ; - the collision in total momentum and kinetic energy of system is conserved before and after the collision is called elastic collision . and the collision in which only momentum is conserved but kinetic energy is not conserved is called inelastic collision .
• second the momentum of any object of mass = m , having velocity = v is given by : P= mv.
• kinetic energy is given by : K.E. = mv² / 2

Part-1 :

• (1) the answer give is right . because it is very clear from the table that for first and second kinetic energy is nit conserved so it is inelastic while in third both conserved so it is elastic .
• (2) the momentum is not conserved in first two but in third it is conserved because total momentum before and after the collision is equal .
• (3) or first two it is inelastic and third one is elastic .as follow from the definition.
• (4)yes relation between mass and momentum : P= mv

Part-2 :

• (1) since momentum and kinetic energy both is not conserved in any of the collision so all three are inelastic.
• (2) in first the momentum id=s conserved but in next two collision momentum is not conserved because momentum before and after the collision is not equal.
• (3) after the collision the crete in rest gains some of the velocity . since momentum is transfered .
