When heat and acoustic energy are radiated from the system, doesn't this mean that the mass must have decreased as we know E = mc^2? I must be wrong, but I can't see where.
In an inelastic collision, the objects involved stick together and move as one, resulting in a decrease in their combined kinetic energy. However, momentum is still conserved because the total mass and velocity of the system remains the same before and after the collision.
In an inelastic collision, some of the kinetic energy is converted into other forms, such as heat and sound. This is due to the objects deforming and the intermolecular bonds being broken in the process of sticking together.
Yes, momentum is still conserved in a perfectly inelastic collision because the total mass and velocity of the system remains the same before and after the collision. However, all of the kinetic energy is converted into other forms, making it a special case of inelastic collisions.
In an inelastic collision between two objects of different masses, the momentum is still conserved. However, the less massive object will experience a greater change in velocity compared to the more massive object.
The coefficient of restitution is a measure of the elasticity of a collision, with a value of 1 representing a perfectly elastic collision. In an inelastic collision, the objects deform and lose some of their initial kinetic energy, resulting in a value of the coefficient of restitution less than 1.
