What is a collision?
Collisions are an occurrence where momentum and kinetic energy are transferred from one object to another.
Why is the dropping height a variable that influences the damage from a collision?
If you drop something without any protection from a low height, the damage would be less than if you dropped that same object from a high place.
Why are the direction and speed variables that influences the damage from a collision?
In a car crash, it would be better for someone to get hit from the back because if you are going in the same direction it would mean you are traveling in fairly the same speed meaning that it will do a lot less damage and be less deadly than if you get hit from the front since you would be going in different directions and probably have different speed so the impact will be a lot bigger.
Why is the type of collision a variable that influences the damage from a collision?
In different situations a different type of collision could be more or less severe.
Would two billiard balls be an example of an elastic or inelastic collision? Why?
It will be an example of en elastic collision since the balls will bounce off of each other
Would a car crash result in the car sticking together be an example of an elastic collision? Why?
No, because when the objects stick together it is an inelastic collision.
What are some variables that play a part in the damage from a collision.
The weight and type of objects since the amount of kinetic energy converted is influenced by the objects, the type of collision, the dropping height, and the direction and speed.
Why are there different methods when attempting to mitigate the damage resulting from a collision?
There are different methods because there are different variables that play a huge part in the damage.
Why is the type of object a variable that influences the damage from a collision?
There will be a huge difference between a bowling bowl being dropped on a phone and a feather being dropped on a phone since the bowling bowl weighs more and will most likely cause a lot of damage, unlike the feather.
How does this information play into your design decisions for how you protected your cargo (ice cube, egg or lego)?
This information plays into the design decisions I made for how I would protect the lego because I knew that an elastic collision would cause more damage to the lego than an inelastic one. Die to that fact I made sure I didn't use any materials that would possibly bounce off of the ground during the collision since that would cause the construction to bounce a couple of times and might fall on a different side or a different direction which might be crucial to the damage done.
What are the two types of collisions?
elastic and inelastic collisions
What are elastic collisions?
when two objects collide and bounce off each other
What are inelastic collisions?
when two objects collide and instead of bouncing off of each other they stick together
