CA2 Review Physics
Projectiles, Vectors, Waves, Power
| Question | Answer |
|---|---|
| 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 doubles this | distance |
| Use to find the speed of sound in air | v = 331 + 0.6 Temp |
| number of waves | cycles |
| measured in Hertz (Hz) | frequency |
| frequency definition via equation | = cycles / time |
| power | how fast once does a certain amount of work |
| When you move mass vertically, the mass is directly releated to this | force |
| how do you combine horizontal and vertical to get resultant | a^2 +b^2 = c^2 |
| A projectile launched from a higher cliff will be moveing___ 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) |
| Period (T) | time to make one wave |
| If you are confused about how to solve a wave problem, maybe you need to use ___ equations. | 2 |
| waves transfer this | energy |
