Forces and Motion
What is a force?
What is kinetic energy?
Energy of Motion
What is a longitudinal wave?
Sound waves
What is conduction?
Transfer by touch
What is an independent variable?
The variable that changes
When my clothes are in the dryer and I feel static on them, where did that come from?
Friction. The clothes rubbed against each other
What is potential energy?
Stored energy,
If my wave has high frequency, high amplitude, low wavelength, does it have high or low energy?
high energy
What is convection?
Transfer of heat through water and gas
A hypothesis
Contact or Non-Contact: Magnetic Force
Non-Contact
What is the law of conservation of energy?
Energy cannot be created or destroyed only transferred or transformed
Where does a sound wave travel the fastest? The slowest?
What is radiation?
Transfer of heat through waves from the sun and light
Can laws change? Why or Why not?
What forces are affected by distance and mass?
Gravity & Magnetism
When I was at Busch Gardens, I rode Sheikra, and it was scary. What energy transformation is seen in this example when Sheikra goes up and down the hill.
Gravitational potential energy is seen when it goes up the hill, and then it transforms into kinetic as it drops.
What is a transverse wave?
Light wave
Radiation
If Antawn is trying to figure out which scissors are the best to cut open a metal rod. He tries 5 types of scissors and writes down if they cut the rod open. What is the dependent variable of the lab?
Name all of the contact forces and non-contact forces>
Contact: Friction, Applied, Normal and Air Resistance.
Non-Contact: Gravitational, Electrostatic, and Magnetism
What is energy?
The ability to do work
Does a gamma wave that is highly dangerous for us to be around, have high energy or low energy? What about a radio wave?
Radio wave: low
Gamma: high
When my sister makes rice, she burns it really bad and it sticks to the bottom of the pot. What heat transfer caused the rice to turn black and stick to the bottom of the pot?
Conduction
What is a limit model of the solar system?
The limit of this model is it does not show me the real size of the planets.
