A collision occurs when two objects come into contact with each other and exert forces on each other in a short period of time. This can result in changes to the objects' motion or shape, depending on factors such as their masses and velocities. Collisions can be categorized as elastic, inelastic, or partially elastic, depending on the conservation of kinetic energy during the interaction.
What else can I help you with?
Give two examples showing the conservation of momentum give one example where momentum is not conserved?
Momentum like mass will always be conserved in any process. Momentum is the product of mass and velocity of the object. It is symbolically denoted as p=m*v where p = momentum, m = mass and v = velocity
Why is it difficult to use the law of conservation of energy to calculate the effects of a collision?
Depending on the type of collission, a variable amount of energy is "lost" in the sense that it is converted from kinetic energy to heat, usually.
Two balls of masses 500gram and 200 gram are moving at valocities 4m s and 8m s respectively on collision they stick together find the velocity af the system after collision?
To find the velocity of the system after the collision, we can use the principle of conservation of momentum. The total momentum before the collision is equal to the total momentum after the collision. Total momentum before collision = (mass1 * velocity1) + (mass2 * velocity2) Total momentum after collision = (mass_system * velocity_final) Using these equations, you can calculate the final velocity of the system after the collision.
What is Principle of conservation of linear momentum?
That means that there is a quantity, called momentum, that is conserved. Momentum is defined as the product of mass times velocity. If you add (product x velocity) for several items, or particles, before and after a collission for example, the total you get will not change. Note that, since velocity is a vector quantity, so is momentum, so if your items move in more than one dimension, you have to use vector addition.
How does the height from which a ball is dropped affect it's bounce?
h=(mgH-x)/mgm is massg is acceleration due to gravityH is height from which it is droppedh is height to which it returnsx is the energy lost due to collission with floor(probably dependant on the coefficient of restitution)well an object falls at 9.6 meters a second so every thing falls at the same time no matter what the height is but the bounce depends on what its made of.Serena Williams (USA)Real answer: Because of gravity. The higher you drop a ball, the more force acts upon it, pulling it towards the ground. After hitting an object, an equal and opposite force acts upon the tennis ball, repelling it. This is known as Newton's 3rd law.
When facing a head-on collission?
brake
When two transmissions interfere with each other?
collission
What collision damage waiver with no excess mean?
collission damage with no excess
Is it safe to throw someone from the vehicle to survive a collission?
The answer depends on the details.
What happen to air when it is compressed?
When air is compressed temperature increases because of the collission and vibration of molecules
What happens to air when air compresses?
When air is compressed temperature increases because of the collission and vibration of molecules
How are car manurfacturers making cars safer for pedestrians?
the manufacturer incoperate hooters on cars and also to note that some car have collission sensors.
I woke up this moring and one of my one month old guppy frys spine was bent upword what caused this?
fast collission with something.
What is a neutron star collision?
That would be a collission between two neutron stars. Since many stars are actually double stars, this can happen now and then.
Why are protocols important to LANs and WANs?
just like, for smooth flow of vehicles, there is need of some rules and regulation. same is application in case of internet or lan and wan otherwise collission, loss data packets will happen
Was the uss frank e evans in Vietnam waters at the time of the collission with the hmas Melbourne.?
Obtain book titled: "Where We Were in Vietnam: A Comprehensive Guide to the Firebases, Military Installations AND NAVAL Vessels of the Vietnam War 1945-1975." By Michael P. Kelley
In a three car rearend collission is car 2 and car 3 at fault whose insurance does car 1 file with?
hopefully, car drivers 2 and 3 have the same insurance supplier. if they dont , TOUGH LUCK, LIFE ISNT FAIR
