Speed
What is the formula for speed?
How do you determine if something is moving?
By using a reference point
What type of energy is the potential to move?
Potential Energy
A bowling ball and a feather are on the same shelf, which one has more potential energy and why?
Bowling ball because it has more mass
What does a speed graph look like if an object is not moving?
A flat line
How do you choose a good refernece point?
Something that is fixed to the earth
Energy of motion is what type of energy?
Kinetic Energy
You are in a moving car, you choose to use the car as your reference point. There is a tree you pass on the side of the road. In this situation, what object is moving?
The tree
On a speed graph, how do you tell if something is moving fast?
The slope is steep
Name three things in this classroom that would make a good reference point?
What are the two factors that affect potential energy?
Mass and height
Fill in the blanks:
The law of conservation of energy states that energy can not be ______________ or ________________ only __________________
Created or Destroyed only Transferred/Changed
Which graph is going faster based on these slopes:
1) 350 miles per 70 hours
2) 640 miles in 80 hours
2) 640 miles in 80 hours
Pick a reference point in the classroom and tell me something that is moving relative to that object.
What are the two factors that affect kinetic energy?
Mass and speed
I am graphing the speeds of two objects. Object 1 has a slope of 5 and Object 2 has a slope of -5. Which object is going faster?
(100 bonus points to each group who can draw the two graphs)
They are going the same speed!
