motion Flashcards
what is speed
distance ina given time
what is velocity
displacement over a given time
if an object moves ina straight line what graph can you show it
a distance time
what is the speed equaltion
distance = speed x time
if a car moves constantly in a circle..
speed is constant but velocity changes cosnantly
the gradient of a dt graph..
shows the speed
what should time be measured in
s
what is acceleration
change in velocity over a given time
acceleration equation
change in velocity (final- initial) = acceleration x time
what does the gradient of a vt graph show
the acceleration so flat can still show movement
what does the area under a vt graph show
distance travelled
average running pace
3m/s
average swimming pace
2m/s
average cycle pace
6m/s
stupid accelleration equation for when you dont have time given
2as= v2 - u2
