Velocity Conversion Activity
Objectives
 The students will be able to convert from km/hr to m/s.
 The students will be able to convert from m/s to km/hr.
Materials
 Calculator
 Velocity Data Sheet
BackgroundTo change from km/hr to m/s multiply by (1000m/1km)
this will remove kilometers from the value and insert meters in its place. T
hen multiply by (1hr/3600s) this will remove hours from the value and insert seconds
in its place.
Example
Change 72 km/hr to m/s Multiply by (1000m/1km)*(1hr/3600s)
(72 km/hr ) * (1000m/1km) * (1hr/3600s) = 20 m/s
To change from m/s to km/hr multiply by (1km/1000m) this will remove meters
from the value and insert kilometers in its place.
Then multiply by (3600s/1hr) this will remove seconds from the value and insert
hours in its place.
Example Change 50 m/s to km/hr
Multiply by (1km/1000m)*(3600s/1hr)
(50 m/s ) * (1km/1000m) * (3600s/1hr) = 180 km/hr
Procedure
Use THIS LINK to get the velocity
data sheet. The data sheet has the data for 14 historical planes and their cruising
or maximum velocities. If the velocity is blank it is unknown. Note the shuttle's
velocity is it's landing velocity. The English measurement systems values are also
included in the chart.
