PROJECTILE WITH VERTICAL INITIAL VELOCITY
DESIGN
Research Question
To calculate the maximum height reached by an object fired vertically, and to compare with the experiment.
Variables
Independent variables: - Launch level chosen.
Dependent variables: - Height reached by the plastic ball and velocity.
Controlled variables: - Projectile launcher, mass of plastic ball (same apparatus used in all trials).
Procedure
Apparatus:
Projectile launcher
Photo gates ±0.25ms-1
2.5cm plastic ball
Ruler ±1cm
Stand with attached ruler
Computer with DataStudio
- Set up apparatus.
- Do 5 trials on each launch level (3 levels) and measure initial velocity using DataStudio. Make sure that the projectile launcher is vertical.
- Measure the vertical height from the photo gates.
- Find the mean initial velocity.
- Calculate and compare height with the experiment.
