Speed
|
def: speed is the distance travelled in unit time
S= D/t S= speed D= distance t= time |
|
|
Velocity
|
def: velocity is the distance travelled in unit time in a stated direction (vector)
V= s/t V= velocity s= displacement t= time |
|
|
Acceleration
|
def: acceleration is the change of velocity in unit time
a= v-u/ t a= acceleration v= final velocity u= initial velocity t= time |
|
|
Motion Sensors
|
connection of a datalogger and computer to the motion sensor
plots: - distance- time graph - velocity- time graph |
|
|
Tickertape timer
|
measures speed & acceleration
marker vibrates 50x per second/ 1/50 s called: tick measured every 10ticks |
