lesson 1
What are the two types of energy we talked about in lesson 1
kinetic and potential energy
What are the different types of colisins
A B C
Do objects bend in collisions
yes
What energy does a cup on a table have
potential
What happens in a B colisin
The damaged object is still, and the other object is moving
What investigation did we do to see if objects bend in collisions
looking at collisions in slomo
What is kinetic energy
movement
What is an example of a permanent change after a collision
a bend or crack
Does movement change when objects collide
yes
When something is moving faster, does it have more or less kinetic energy
more
When does a change happen in a collision
the split second after the objects touch
What happened when we pointed a laser at a mirror on an object and then dropped something on the object in another spot
The laser's reflection changed
True or false: Energy is never created or destroyed
true
Did the baseball bat do in the slow-motion collisions
