Air Resistance impact on Range - Coggle Diagram
Air Resistance impact on Range
Quantities that cause a change in Air resistance (One of them can be changed to change Air resistance and analyse impact of this change on the range)
Streamlined vs other shapes that are less aerodynamic
not useful to test change in range if only velocity is changed because that will not help show the effect of air resistance. Range is impacted by the velocity irrespective of whether air resistance acts or not
Affected by different altitude
Projectile launched in a helicopter vs that launched on ground would encounter different air density therefore different air resistance
Is affected by temperature and humidity
Could conduct experiments on different days e.g. hot and humid vs cool and dry
Problem: Conducting the experiment on different days is time consuming, and experimenting on different altitudes is impractical. Therefore, changing medium density is not practical.

What affects range apart from Air resistance (control if possible)
Horizontal component velocity, which increases by increasing the
Must be less than 90 degrees as vertical only motion will not achieve a range at all. Launch angle should also be greater than 0 to be able to have a positive time of flight
Greatest range without air resistance is achieved at an angle of 45 degrees. Even with air resistance, this would be a good angle to experiment at, as it is the middle of the restriction set in the above branch. This angle will give a decent range and time of flight.
Time of flight: increases by increasing the
Vertical component velocity
Uni level motion is preferable due to its simplicity. Launch height to be 0.
