Stoppimg Distance Flashcards
1
Q
Light hat card
A
Known value of card, light bath and data logger, will find VELOCOTY
2
Q
How to do stopping
What’s the relationship and why?
A
Push stuff at different amounts through a light gate , will give you INITAL velocity
Then measure distance needed to stop
2) relationship is v2 is proprtinsl to distance trsvlled, because we assume all the ke is transferred into the al energy as constsnt frictional force does work against to decelerate
3
Q
Why is repeats hard
A
If pushing each time , repeats could be hard a block of wood, ensure you get many points
Or use ramp etc , UTS yeah interrupts card to find INITAL v and resulting distance should be proprtinsl c2 to s
