1.    You have one cylinder with a volume of 100 cm3. What would be the volume of a second cylinder if the radius was 20% bigger and the height was reduced to 80%

2.     The formula for universal gravity is defined by this equation.  , where G is a constant, M1 is the first mass, M2 is the second mass, R is the separation distance and Fg is the force of gravity. If the force of gravity between two large objects is 500N. Determine the force of gravity if the mass of the first object increase by 43%, the mass of the second object decreases to 87% and the separation distance decrease to a third.

Making connections activity:

*      This activity is designed to show students how much energy the average vehicle consumes on a typical commute

*      Students were to research their family vehicle to determine the mass of their largest vehicle

*      Then using Gmaps Pedometer determine distance of a typical commute. In our example we used a commute from the North end to the South end of the city

*      Based on this commute, the students were to estimate the number of possible stops en route to work. (i.e lights, stop signs, etc)

*      The following assumes were made.

*      the maximum speed was 60kmh

*      Overall efficiency was approximately 5.8%
