When two bodies collide why they do make noise?
When two bodies collide, the impact generates vibrations in the air molecules surrounding them. These vibrations travel as sound waves to our ears, where they are interpreted as noise. The intensity and pitch of the noise depend on factors such as the speed and mass of the colliding bodies.
What is the meaning of formula for resultant velocity?
There are several layers of complexity to resultant velocity of a colision based on the assumptions used. In a cohessive colision, two or more bodies colide and fuse into one. The resultant velocity is the speed and direction the new body will travel due to the momentum of the original bodies. In a non-cohessive colision, two or more bodies colide, but subsequently rebound away from each other based on the area of contact and momentum of the relevant bodies. The resultant velocities are the speed, direction, and rotation the bodies after the crash.
Can the relative velocity of two bodies be greater than the absolute velocity of either?
Yes it can be!!! If two cars on a straight road head directly toward each other at a speed of 60mph (relative to the road), the velocity of one relative to the other is 120mph. This example arbitrarily uses the road as the reference for each car's speed, but there really is no such thing as "absolute velocity" and both cars would have a velocity of about 1000mph relative to the center of the Earth. According to Einstein's principles of "Relativity" all velocity is relative.
Why do the velocity of free falling bodies not change?
The velocity of free falling bodies does change due to gravity accelerating them towards the ground. However, in the absence of air resistance, the acceleration due to gravity causes the velocity to increase at a constant rate, resulting in a uniform change in speed over time. This creates the perception that the velocity is not changing, but in reality, it is increasing continuously.
What are the sample problems in free falling bodies?
Some sample problems in free falling bodies include determining the time it takes for an object to fall a certain distance, calculating its final velocity upon impact with the ground, and finding the height from which an object was dropped based on its impact velocity. These problems typically involve using equations of motion like the kinematic equations to solve for various unknown quantities.
Damage is more when two bodies collide from opposite directions than when they collide at any other angle.Is it due to the momentum of the objects or their relative velocities?
The increased damage when two bodies collide head-on is due to the momentum of the objects, which is the product of their mass and velocity. When two bodies collide from opposite directions, their momentums add up, resulting in a greater force of impact compared to collisions at other angles where momentums may partially cancel out.
What happens when there is a head on collision of two bodies moving at uniform velocity?
they both crash
Define high and low velocity impact?
In mechanics, an impact refers to the shock or force produced when two or more bodies collide. High and low velocity impacts basically differ in the speed at which the objects collided. Low velocity impact is normally under 30 mph while high velocity impact is above.
What does conserving momentum mean?
It mean that when two bodies collide in an closed or isolated environment(where there is no external agent) there is no net change in the products on thier masses and thier velocity before and after collision.It describes the fact that when two bodies collide in an isolated or closed system(where there is not physical agent)there is no net change in the product of thier masses and their velocities before and after collisions.
There are three collision that make up every collision what happens during the third collision?
The soft tissues of the passengers' bodies collide with the more solid parts of the body, such as the skull, ribs, or pelvis.
Why does heavenly bodies in your solar system does not collide with each other?
They might collide eventually. The reason they don't collide all the time is that they have stabilized. What happens here is that (1) the distance between such objects is very large, on average, and (2) they remain relatively stable in their corresponding orbits. However, it is possible for the orbits to gradually change over time, making it possible for collisions to happen eventually.
What happen when worlds collide?
When worlds collide, it can lead to a variety of consequences depending on the context. In astrophysics, the collision of celestial bodies can result in the formation of a new celestial body or the destruction of existing ones. In a metaphorical sense, when different ideas or cultures collide, it can lead to conflict, synergy, or the creation of something new.

Is it true that asteroids never actually collide with planetary bodies?
No, it is not true. They do hit planets sometimes.
