Sheldon from the Big Bang explains physics Why is Science Important?
"The most incomprehensible thing about the world
is that - Einstein
Describe motion by using: A) Average Speed
Average Speed can also be written ...
120 miles/hr per = divided by
Could mean travelled 120 miles in one hour
OR ....
60 miles in ...
1/2 hour (30 minutes)
30 miles in ...
15 minutes
OR 15 miles
in 7.5 minutes
100 km/hr » 60 mph
miles/hour
Average Speed = Δd/Δt
Speed = Δd/Δt
= 5m/2 sec
= 2.5 m/s
Speed =Δd/Δt
3 m/s = Δd/1.5 sec
Δd = 4.5 m
Motion Map
3 m/s for 1.5 seconds
Δd = 4.5 m

4 m/s = 10 m/t
(4 m/s)t = 10 m
t = 2.5 seconds
Motion Map
t = 2.5 seconds
