In collisions of macroscopic bodies, some kinetic energy is turned into vibrational energy of the atoms, causing a heating effect, and the bodies are deformed.
The formulae for the velocities after a one-dimensional collision are:
where
- va is the final velocity of the first object after impact
- vb is the final velocity of the second object after impact
- ua is the initial velocity of the first object before impact
- ub is the initial velocity of the second object before impact
- ma is the mass of the first object
- mb is the mass of the second object
- CR is the coefficient of restitution; if it is 1 we have an elastic collision; if it is 0 we have a perfectly inelastic collision, see below.
In a center of momentum frame the formulas reduce to:
- va = − CRua
- vb = − CRub
For two- and three-dimensional collisions the velocities in these formulas are the components perpendicular to the tangent line/plane at the point of contact.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
