A ball is rolling down a hill. What kind of energy does it have?
Kinetic because it is moving
400
How does friction slow down a roller coaster car?
It converts the kinetic energy to thermal energy.
400
As a roller coaster is rolling down the track, is it transforming/converting
It is losing potential energy and gaining kinetic energy

half an hour
400
What has more PE?
Watermelon of mass 18kg ? or Feather of mass 3kg
the watermelon because it has more weight.
The MORE mass the MORE Potential Energy
500
What point on the roller coaster has the GREATEST Potential energy and WHY?
Point A because it is the highest
500
When a roller coaster is going up the hill the energy is transforming/ converting
It is losing Kinetic and gaining potential energy

Tate kicked a soccer ball and it went 5ft per second.
Jack kicked a soccer ball and it went 250 ft per minute.
Which one kicked the ball faster? (explain how you know)
Tate kicked the ball faster there are 60 seconds in minute so 5 X 60 = 300
Which means the ball she kicked was traveling at 300 feet per minute.
500
