into the detailed answers to the Collisions and Conservation of Momentum worksheet Question 1 What is the principle of conservation of linear momentum Answer The principle of conservation of linear momentum states that the total linear momentum of an isolated system remains constant even when internal forces act within the system Explanation Linear momentum is a vector quantity defined as the product of an objects mass and its velocity p mv where p is the linear momentum m is the mass of the object v is the velocity of the object In an isolated system the total momentum before a collision equals the total momentum after the collision This means that momentum is neither lost nor gained during the interaction it is simply transferred between objects within the system 3 Question 2 Define elastic and inelastic collisions Answer Elastic Collision An elastic collision is a collision where kinetic energy is conserved In other words the total kinetic energy of the system before the collision is equal to the total kinetic energy after the collision Examples Collision of billiard balls Collision of two perfectly rigid objects Inelastic Collision An inelastic collision is a collision where kinetic energy is not conserved Some of the kinetic energy is lost or transformed into other forms of energy such as heat sound or deformation of the objects Examples A car crash A ball of clay hitting a wall Question 3 Explain the relationship between impulse and momentum Answer Impulse is the change in momentum of an object It is calculated as the product of the force applied and the time for which the force acts Impulse J Force F x Time t Momentum p Mass m x Velocity v Change in momentum p Impulse J Therefore impulse equals the change in momentum Question 4 Calculate the final velocity of two objects after an elastic collision Answer To calculate the final velocities after an elastic collision we need to apply the principles of conservation of momentum and conservation of kinetic energy Conservation of momentum mv mv mv mv 4 Conservation of kinetic energy 12mv 12mv 12mv 12mv Where m and m are the masses of the objects v and v are the initial velocities of the objects v and v are the final velocities of the objects By solving these equations we can find the final velocities of the objects Question 5 Discuss the role of the coefficient of restitution in collisions Answer The coefficient of restitution e is a dimensionless number that describes the elasticity of a collision It represents the ratio of the relative velocity of separation after the collision to the relative velocity of approach before the collision e v v v v Values of e e 1 Perfectly elastic collision kinetic energy conserved 0 e 1 Partially inelastic collision some kinetic
