How do you calculate rate of anything….ex:
miles per hour
What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?
What if you walked 6.00miles±0.05miles in 2.00hours±0.05hours?
Compare % uncertainties?
• Example A: “What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?” =3.0miles/hour ±33% • Example B: “What if you walked 6.00miles±0.05miles in
2.00hours±0.05hours?” =3.00miles/hour ±3.3% Why does example B have less uncertainty than sample A?
What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?
What if you walked 30.0miles±0.5miles in 10.0hours±0.5hours?
Compare % uncertainties?
• Example A: “What if you walked 6.0miles±0.5miles in 2.0hours±0.5hours?” =3.0miles/hour ±33% • Example C: “What if you walked 30.0miles±0.5miles in
10.0hours±0.5hours?=3.00miles/hour ±6.7% Why does example C have less uncertainty than sample A?
