If Valeria is changing her velocity, we say she is...
What is accelerating?
This is how you can change the potential energy of an object
What is change the height? (or mass...)
The type of heat transfer that happens when Ester gives Christina a hug
What is conduction?
Like charges do this
What is repel?
The height of a wave
What is amplitude?
Attractive force between any two masses
What is gravity?
Maroosh rolls a 6 kg bowling down the lane at 5 m/s and gets a strike. The ball has this much momentum.
What is 30 kg m/s?
Heat moves through these materials quickly
What are conductors?
This provides the energy of a closed circuit
What is the battery?
If a wave has a high frequency, you know this about its wavelength
What is short?
A distance vs. time graph for an object moving with a constant speed looks like this... (draw it)
What is a graph with constant slope?
The total momentum of two objects with equal masses and speed moving towards each other
What is 0 kg m/s?
It takes a lot of energy to change the temperature of water. What does this mean about its specific heat?
What is a high specific heat?
This is what a parallel circuit looks like with circuit symbols... (draw it!)
What are 2 (or more) separate loops
A wave with a frequency of 6 Hz and a wavelength of 3 m moves at this speed
What is 18 m/s?
A force that keeps objects going in circles
What is centripetal force?
Whenever we change the energy in an object, we do this to the object
What is do work?
When Xavier puts his energy drink into the fridge, it cools down until it reaches the same temperature as the inside, reaching this.
What is thermal equilibrium?
If the distance between two charges is divided by 2, the electric force is multiplied by this number
What is 4?
When light rays bend when they move from air to water, it is called this
What is refraction?
Ricardo has a mass of 55 kg. The scale pushes up on him with this much force
What is 550 N?
Chris uses this much power when he moves a table 5 m by pushing it with a force of 20 N in 4 seconds
What is 25 W?
Troia adds 350 J of heat energy to 70 g of coffee. The change in temperature is this. (The specific heat of coffee is 4.2 J/g C)
What is 1.19 degrees Celcius?
We can create this by moving magnets near a wire
What is current?
The pitch of a motorcycle sounds like this when it comes towards you
What is higher than normal frequency?
