Rank each position from least to greatest PE.

What is the relationship between starting height and PE?

CFS:

• Accurately describes energy types (KE/PE) by analyzing the movement of objects

• Student describes the impact and relationship between changing variables (height and energy)

"I notice that the (higher/lower) the object, the (more/less) PE there is. As the starting hight decreases, the PE (increases/decreases)."

What is the relationship between starting height and KE?

CFS:

• Accurately describes energy types (KE/PE) by analyzing the movement of objects

• Student describes the impact and relationship between changing variables (height and energy)

"I notice that the (higher/lower) the object, the (more/less) KE there is. As the object continues to fall, the KE (increases/decreases)."

If the Hulk starts with 100 units of PE, what is the maximum amount of KE that he can receive? _________

What conclusions can be drawn about the final direction of movement in this collision? (assume the mass of each object is equal.

CFS:

• Accurately identifies the changes to each object in a collision

• Accurately describes the relationship between force, and motion

"I think the total force in the collision will cause the objects to move (left/right). This is because ... "

What conclusions can be drawn about the final direction of movement in this collision? (assume the mass of each object is equal.
