During a collision the forces on the colliding bodies are always equal and opposite at each instant. These forces cannot be anything but equal and opposite at each instant during collision. Hence the impulses (force multiplied by time) on each body are equal and opposite at each instant and also for the entire duration of the collision.
Meaning of inelastic collision is some energy of collision transforms into potential energy, either by changing shape or heat or sound etc. So, in a perfect inelastic collision, the maximum amount of energy is converted into potential energy. And by conservation of energy, maximum kinetic energy is lost.
I think all of the existing answers miss the real difference between energy and momentum in an inelastic collision. We know energy is always conserved and momentum is always conserved so how is it that there can be a difference in an inelastic collision? It comes down to the fact that momentum is a vector and energy is a scalar.
In any collision, the rate at which mechanical work is being done on each object (i.e., the mechanical power imparted) is not necessarily the same at any given time. However, conservative forces have the ability (by definition) to balance things out, so that the time integrals of the power imparted in each case end up being equal.
An inelastic collision is a collision where the kinetic energy is not conserved. Some of the lost kinetic energy is converted into other forms of energy such as heat energy and potential energy and sound energy etc. Strictly speaking heat energy is a form of kinetic energy of the molecules vibrating in random directions.
Apr 9, 2015 at 11:54. 4. I'm sure this is a duplicate, though after a quick search I can't find an obvious duplicate. The answer is that the wall does move. The wall is connected to the Earth, and when the ball hits the wall it makes the Earth move to conserve momentum. However the mass of the Earth is so great the velocity change of the Earth ...
Finding force exerted in an Inelastic Collision. I did a lab today in Physics in which we launched ball from a spring loaded cannon directly into a pendulum that captured the ball, held it, and swung upwards with it (representing a totally inelastic collision). One question in particular has confused me:
Even in a vacuum, the inelastic deformation would result in an increase in the temperatures of the blocks. An increase in temperature means there is an increase in the kinetic energies (KE) of the atoms and molecules of the blocks, i.e., an increase in KE at the microscopic level. In effect, the macroscopic KE of the blocks associated with ...
Generally, when an inelastic collision occurs, the nonrelativistic energy of two observable objects is not conserved because some energy has been transformed into other forms such as heat and sound. I understand the fact that the energy of the entire isolated system is conserved if the total mass of the system is a constant.
Inelastic Collision: In an inelastic collision, a portion of the compressive energy is transmitted through the ball's material. In effect, the energy associated with the pressure wave has disconnected from the rebound kinetic energy of the ball, resulting in its reduced height on the bounce. Reflection: The pressure wave travels through the ...
