Thank you We sneak And here's your shmoop du jour

00:05

brought to you by elastic Without it superman just wouldn't

00:08

look the same You need that elastic there personally or

00:12

which of the following can be classified as elastic collisions

00:15

Like two answers And here the option remember both is

00:20

howard what's an elastic collision Here's a hint it has

00:23

nothing to do with our socks falling down that's more

00:25

of a well elastic failure An elastic collision occurs when

00:30

kinetic energy is maintained after a collision Put it in

00:34

highly scientific terms elastic collisions are banksy and in elastic

00:38

collisions are sticky Now in the real world there aren't

00:41

many collisions that air completely elastic In the real world

00:44

elastic collisions usually create heat and involved d formation like

00:49

this guy and that's The problem with the real world

00:52

It makes our beautiful physics a little well messy But

00:56

there are a lot of partially elastic collisions A tennis

00:58

player hitting a volley a soccer player heading the ball

01:02

into the goal us dominating and bumper cars We'd like

01:05

to do that And you know athletes like us are

01:07

used to those kind of elastic collisions Ma'am let's take

01:10

a look at our options here When a rubber ball

01:13

is thrown against a wall it'll bounce back Yep bounce

01:16

equals elastic so option a is one of our correct

01:18

answers How about option b two discs bouncing off each

01:22

other Well that's definitely elastic so that's our second answer

01:25

Let's Take a look at the other two incorrect choices

01:27

below because of well you know learning We guess if

01:30

two blocks collide and slide together well that would be

01:33

in elastics since they're sticking together and kinetic energy is

01:37

lost and option d is wrong too If a particle

01:40

hits a hard service and doesn't bounce off well that's

01:43

not an elastic collision Well just remember objects in an

01:46

elastic collision Maintain kinetic energy After all elastic is stretching

01:50

and bouncy right which is a good thing because superman

01:53

and sweat pants uh well just looks like our uncle 00:01:56.343 --> [endTime] murray
