Luke Skywalker is traveling to different planets. He notices a difference in the amount of force keeping him on the ground. What force is this?
Gravity.
Darth Vader moves the Death Star in space. It is easy for him to move quickly with it because there is no resistance. What two things are not in the way for the Death Star to move quickly?
Friction and Gravity
What is an independent variable?
Give an example from our experiments.
Changing on purpose/cause
Amount of books/height of plant/type of magnet

A. In front of him
B. Behind him
C. To the left
D. To the right
B. Behind him
What is texture?
Give 2 examples.
how something feels when you touch it
ex: smooth, rough or soft.
Paul pushes a box to the right with 20N of force. Sammy pushes the same box to the left with 15N of force. Which direction is the box going to move?
To the right/5N to the right
Chewbacca runs on different planets to help fight against droids. His speed is effected when on different planets. These different planets are made of sand, ice, and woodlands. What could be the reason he runs at different speeds when on different planets?
The texture of the ground on each planet/friction
Princess Leia wants to grow plants. She wants to see if the amount of sunlight changes the growth of her plants. If she is changing the amount of sunlight and measuring the height of the plant, which one is the independent and dependent variable?
Independent- amount of sunlight
Dependent- Height of plant growth
How can I change the amount of speed an object is going down a man made ramp?
Texture of ramp/height of ramp
What is friction?
Give an example.
the force that resists the motion of two objects rubbing against each other in opposite directions.
Teacher approved answer.
Amanda pushes Suzie on a swing. Why does Suzie come back on the swing?
Gravity
A car is speeding at 100mph. Once the driver is no longer pressing on the gas to keep the car moving, why does the car begin to slow down?
Wind resistance/friction/gravity
Anakin Skywalker is racing his podracer in the big race. He wants to be able to move faster. He is wondering if adding more or less materials will affect his speed. Which will help him be faster in the race?
Less materials will make it move faster.
Yoda and Obi Wan are practice fighting with light sabers. Yoda has the force of 40N and Obi Wan has the force of 30N. If both sides use all of their force when swinging their light sabers, who would win? Explain why.
Yoda would win because he has 10 more force than Obi Wan.
