A collision in one dimension is when two objects come into contact with each other in a straight line, without any movement in other directions.
The conservation of momentum in one dimensional collisions states that the total momentum of the objects before the collision is equal to the total momentum after the collision. This means that the total momentum is conserved, even though the individual momenta of the objects may change.
The coefficient of restitution is a measure of how much energy is lost during a collision. In one dimensional collisions, the coefficient of restitution can be calculated using the ratio of the final velocity of separation to the initial velocity of approach.
Yes, the relative velocities of two objects can be different before and after a collision in one dimension. This is because the direction of the velocities may change during the collision, resulting in a change in the relative velocities.
Some real-life examples of collisions in one dimension include a car colliding with a barrier, a ball bouncing off a wall, or a billiard ball striking another ball on a pool table.
