The frame of a vehicle is designed to absorb energy in a collision through deformation of crumple zones built in to the structure of the vehicle In this case, it's the golf club that undergoes the change in velocity due to its collision with the golf ball. The interior passenger compartment however is designed to be strong so that damage to the occupants is minimized.

This thermal energy speeds up the motion of the reactant molecules, increasing the frequency and force of their collisions, and also jostles the atoms and bonds within the individual molecules, making it more likely that bonds will break. When calculating the force exerted during a collision, the focus is on the change in momentum of the object experiencing the force So, if the collision doesn't have enough energy, the molecules, or in this case the atom and the molecule, will just bounce off of each other
If you do have enough energy, the colliding molecules will vibrate strongly enough to break bonds.
In an inelastic collision, the total final kinetic energy of the system is less than the total initial kinetic energy of the system because some of the energy is dissipated as other forms of energy In a perfectly inelastic collision, the objects stick together and move together after the collision. Hello, my book says that catalysts may increase the frequency of collisions, change the relative orientation of the reactants, or reduce intermolecular bonding within reactant molecules. Conservation of momentum can be used to predict the motion of objects after a collision
Let's try two practice problems together. If objects stick together, then a collision is perfectly inelastic When objects don’t stick together, we can figure out the type of collision by finding the initial kinetic energy and comparing it with the final kinetic energy. In this video, david solves an example elastic collision problem to find the final velocities using the easier/shortcut approach.
Collision theory says that particles must collide in the proper orientation and with enough kinetic energy to overcome the activation energy barrier
So let's look at the reaction where a reacts with b and c to form ab plus c.
