How does your speed affect a collision?
When traveling at a higher rate of speed you will have more force in case of collision.
What is elastic and inelastic collision?
In an elastic collision, no kinetic energy is lost, and the relative speed of separation of the objects after the collision is the same as the relative speed before the collision. In an inelastic collision, part of the elastic energy is lost, and the relative speed after the collision is less.
Why would a high-speed collision between two cars cause more damage than a low-speed collision between two cars?
There is more kinetic energy involved in the case of a high-speed collision.
Explain why a high-speed collision might cause more damage to vehicles then a low- speed collision?
because the high speed collision has more energy that it is using when the damage is occuring love Shanika L. Jackson♥
Why does a high-speed collision between two cars have more damage than a low-speed collision between two cars?
There is more kinetic energy in the collision involving the high-speed cars than there is in the collision involving the low-speed cars, resulting in a greater amount of force exerted on each car, prompting more damage.
What is final velocity minus initial velocity divided by time used for?
That expression represents average speed during the time.
How does your speed affect a collision?
When traveling at a higher rate of speed you will have more force in case of collision.
In two boys of unequal weights running towards each other with the same speed meet lead-on what is the result of the collision?
The lighter boy will be moved backwards by a force equal to the difference in their masses.

Why a high speed collision between two cars would cause more damage than low speed collision between the same two cars?
There's more force exerted in the high speed collision.
Why would a high-speed collision between two cars cause more damage than a low-speed collision between two cars?
There is more kinetic energy involved in the case of a high-speed collision.

Explain why a high-speed collision may cause more damage to vehicles than a low-speed collision does?
More kinetic energy involved.
Why a high speed collision may cause more damage than a low speed collision?
At higher speeds, there is more kinetic energy involved.
What is the speed of the car and truck as they move forward connected together after the collision?
It depends on their initial speeds and masses. The speed can be worked out by: mcarucar + mtruckutruck = mbothvboth where u = initial veloicty m = mass v = final veloicty remember u and v are vectors so will have direction!
