What is the unit of force
NEWTONs
Does at least one of the things have to be moving fr a collision to happen?
yess
names 10 elastic objects
correct
What are the two kinds of energy
Kinetic and Potential
Deform
to bend distort or change shape
Name three factors that affect a collision
weight, mass. size, speed, durability, friction, material, gravity, texture, fragility, height, etc.
if you put 20 elephants on a piece of woods will it bend
yes
What is energy
Energy is what makes things happen, like move, grow, change temperature, or change
Elastic Limit - give example
the maximum amount of defomation an object can withstand before unitl it will deform permantently
building bending under weight and hen breaking
Describe A, B, and C collision
A- =[] []
B- [] []=
c- =[] []=
WHat objects bend?
all
ALL types of PE
Elastic, chemical, gravitational, nuclear, mechanical, electrical, sound, radiant, thermal
Energy transfer
Energy transfer is the movement of energy from one object, system, or location to another
how would you say collision and elststicity affect eachother
may break or not break, duablitlity
If it doesn't bend as easily, what does it have a tolerance to
It has a tolerance to deformation
At what point of a ball rolling down a hill are the kinetic and potential energy equal?
kinda on the way up? make sure to change
equation for KE and PE
KE=1/2mv2 PE=mgh
