Forces and Motion
What do we need to apply for an object to move?
What is Force?
Which pair(s) of magnetic poles are attracted to each other?
What is North and South?
What term has the definition of "takes in" as in "takes in water"
What is Absorption?
A wagon stops after moving across a surface for awhile. What caused it to stop?
What is friction?
True or False: Heavier objects need more force than lighter objects to move the same speed.
What is True?
Which pair(s) of magnetic poles are repelled by each other?
What is North and North, and South and South?
True or False: Can you pull energy out of an object?
What is false?
What are the 2 types of energy that are involved with motion?
What are Kinetic and Potential Energy?
There are 3 boats: Blue, Orange, and Grey. Each boat has a speed change of 5 km/h. Did all 3 boats experience the same amount of force?
What is yes, all 3 boats experienced the same amount of force because they all had the same speed change?
When you move 2 repelling Poles toward each other, what happens to Potential Energy?
What is "it will increase"?
An butterfly interacts with 3 different types of light. UV is absorbed, X-ray is transmitted, and Infrared is reflected. Which causes a reaction in the butterfly?
What is UV?
Some friends are playing croquet. One player uses their mallet to hit their ball into another ball.The first ball slows to a stop, and the second ball starts rolling. The friends come up with explanations to describe energy movement in the scenario. Which friend is correct?
What is Jen says that energy from the the mallet was transferred to the first ball and then to the second ball?
A asteroid hits two different moons. Moon 2 has more mass than moon 1. Both moons had the same amount of speed change. Which moon experienced the greater amount of force?
What is Moon 2?
Magnetic Field Lines look different depending on whether the magnetic poles are repelling or attracting. What do attracting magnetic field lines have when attracting vs. repelling?
What is attracting Poles have the middle lines connected?
There are 3 types of light interacting with an object: Red light, UV rays, and X-rays. Red light and UV are absorbed, and X-rays are transmitted. Which type(s) has a reaction with the object? Can there be more than 1 kind of reaction?
What is Red and UV? What is yes because they are different types of light?
What is the unit we use to measure energy?
What are Newtons?
`A team of engineers is developing a new water slide for a theme park. The riders of the slide will climb several flights of steps to reach the top of the slide and will sit in a round inner tube as they slide down. The engineers are testing a computer simulation to measure the kinetic energy that the riders will have on the slide. The kinetic energy will be based on the potential, or stored,energy and will depend on mass and speed. The engineers want to develop a way to transfer the most kinetic energy to the riders to make their trip down the slide as fast as possible.Which of these solutions would increase the kinetic energy in the model slide?
What is increasing the number of flights of steps that the rider will climb?
A student rubs a comb on a cloth. She then holds the comb 30 centimeters above some small pieces of paper on a table, but the paper does not move. When the comb is moved closer to the paper, the paper moves through the air to the comb. Why the paper does not move toward the comb when the comb is farther away?
Hint: Static
What is the attractive field from the comb is weaker farther from the comb?
What are all the types of light on the electromagnetic spectrum?
Radio, Micro, X-rays, Infrared, Gamma, Visible light, UV
A student makes a balloon cart to investigate how combined forces create motion. The student creates a simple cart by attaching wheels to a small piece of cardboard. The student attaches a straw with a balloon on one end as shown in the picture so that any air coming out of the balloon flows in one direction. The student blows up the balloon, sets the cart on the tabletop, and lets go. Air flows out of the balloon and through the straw, but the cart does not move. Which of these explains why the car does not move?
What is the force on the cart from the air in the balloon and the friction on the tires is balanced?
