Science, Physics - Motion & Wave +Sound Flashcards
1
Q
formula for speed
A
speed = distance/time
2
Q
formula for distance
A
distance = speed x time
3
Q
formula for time
A
time = distance/speed
4
Q
acceleration graph
A
goes up (/)
5
Q
stationary/constant speed graph
A
goes straight (-)
6
Q
deceleration graph
A
goes down ()
7
Q
sound
A
- produced by vibrations traveling in mediums (solid / liquid / gas)
- cannot travel in a vacuum (empty space)
8
Q
how to calculate how far an object has traveled
A
- triangle shaped
- area = 1/2 x base x height
9
Q
how to calculate how far an object travel at a constant speed
A
- square
- area = base x height
10
Q
waves
A
- transfer energy & info without transferring any material with no mass
- has to have one trough & 1 crest
11
Q
trough
A
very bottom of the wave
12
Q
crest
A
very top of wave
13
Q
amplitude
A
distance from resting position to crest/trough
14
Q
wavelength
A
distance between crest-crest or trough-trough
15
Q
frequency
A
- no. of waves per second
- what you see (graphs)
