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
everything
What are the two kinds of energy
Kinetic and Potential
when does energy transfer happend
When the objects in a collision touch
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, but also probably break
What is energy
Energy is what makes things happen, like move, grow, change temperature, or change
How does a rougher object affect the friction
It creates more friction and more heat
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
How does wind affect the speed
It can slow down or speed up an object
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
At what point of a ball rolling down a hill are the kinetic and potential energy equal?
when the ball is a the bottom of the hill
True or False: Increasing the mass causes exponential growth
false
equation for KE and PE
KE=1/2mv2 PE=mgh
