inelastic/elastic collision
what type of collision does NOT conserve the net kinetic energy
what is inelastic collision
when the tectonic plates shift underwater making an earthquake what results
what is a tsunami?
what variable is defined by M*V or Mass times velocity
what is Momentum (p)
what types of energy are within a system
what is internal(spring or thermal works), potential, and kinetic energy
define what momentum is
what is a representation of the inertia of an object
what type of collision conserves the net kinetic energy
what is elastic collision
describe a scenario where a collision would result in an explosion
up to mr newman's discretion
what type of energy is defined by the equation
1/2(m)v2
what is kinetic energy
no matter what type of collision happens what is always conserved?
what is momentum
define what impulse is
what is the rate at which momentum changes
is the initial kinetic energy and the final kinetic energy ALWAYS the same
what is no
when a major collision happens, and kinetic energy can not go anywhere, what happens to the resulting energy
what is released as a shockwave of sound or heat
the change in momentum called as and what is its equation
what is impulse; (delta)p = Ft
two individuals are standing still on frictionless ice and push off of each other and go in different directions what is their net final momentum
if i throw a paper towel at my brother how much will his being angry affect the momentum of the paper towel
what is physics doesn't care about your feelings
if two objects were to be moving, hit each other and stick together moving together, what type of collision is it
what is inelastic
describe how a tsunamis waves are formed
what is traveling under water until it hits the shore where the energy is bunched up creating large ripples (waves) that crash onto land
what is the equation for the center of mass of a system
what is the COM = sum of each mass*distances from 0 point /total mass
COM = m1d1+m2d2.../m(total)
why do cars have crumple zones?
what is to slow down a collison raising time to lower the force
describe the relation and diffrences between momentum and kinetic energy
up to mr newman's discretion
when a car crashes into a wall of bricks it stops, it also does the same when it hits a wall of pillows. is the momentum the same at the start of each system and is the momentum the same at the end of each system
what is yes and yes
how is a meteor strike similar to a tsunami?
this is up to mr newman's discretion
what equation was momentum derived from?
net Force = instantaneous change in mass*velocity/instantaneous change in time
F(net)= d(mv)/d(t)
if a rocket ship is moving upwards whilst burning fuel to accelerate upwards to counteract the downwards acceleration of the earth's gravity so that it has a constant velocity. is its momentum changing or staying constant
what is constant
if there is 700 kg*m/s of momentum in a system and something inside the closed system exerts 20N of force over 2 seconds how much momentum is there at the end of the force
what is 700 kg*m/s, momentum is always conserved in a closed system
