Ca2 Review S26

kinematics, vectors, projectiles, centripetal force, waves

QuestionAnswer
Speed of all EM waves c = 3x10^8 m/s
objects placed on the focal point of a converging lens no image formed
Convex mirror and concave ____ have the same properties lens
An echo ___ the distance that a wave must travel. doubles
Use to find the speed of sound in air v = 331 + 0.6 Temp
measured in Hertz (Hz) frequency
frequency definition via equation = cycles / time
A projectile launched from a higher cliff will be moving___ when it hits the ground. faster
A projectile launced at a slower upward velocity will reach a ___ height. lower
objects placed in front of a diverging lens virtual upright smaller image formed
Convex mirror and concave ____ have different properties mirror
Greek letter "lambda" (λ) wavelength
relates wave speed to frequency and wavelength v=λ∙f
Equation used for echo questions v = d/t
inversely related to frequency; f = 1/? Period (T)

If you are confused about how to solve a wave problem, maybe you need to use ___ equations. 2
waves transfer this energy
Force that points toward the center of circular motion centripetal
As you coast up a hill, you gain PE (potential energy) and lose ____ KE (kinetic energy)
The total ____ remains the same in an isolated system. ME (mechanical energy)
When the initial and final speeds are the same, you are moving at a... constant velocity.
When the initial and final speeds are different, you are... accelerating.
You know angle Θ and the adjacent side, find the hypotenuse using... cosine (CAH)
You know angle Θ and the hypotenuse, find the opposite side using... sin (SOH)

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
