2. Hypothesis and Independent and Dependent variables
Hypothesis: The angular velocity of the knee and linear velocity of the hip is greater in the bodyweight hip thruster than the angular velocity of the knee and linear velocity of the hip in the weighted hip thruster. As a result, the jumping height would be greater in the bodyweight hip thruster than the weighted hip thruster.
Independent variables: Barbell or no barbell
Dependent variables: knee and hip angles and angular and linear velocity

3. Initial and Final Position of Angular Velocity for knee; Bodyweight version

4. Calculations for Angular Velocity for Knee; Bodyweight Version
Angular Velocity equals Angular Displacement over time.
Angular Displacement equals final angle minus initial angle.
Final angle- 158 degrees - Initial angle- 59 degrees = 99 degrees
If converted to radians: 57.3 degrees in 1 radian. 99/57.3= 1.73 radians. Rounded to nearest hundredth.
Time it took: .6 sec
Angular Velocity= 1.73 radians/.6sec= 2.88 radians per sec

5. Final and Initial Positions for Linear Velocity for Hip; Bodyweight version

6. Calculations for Linear Velocity of Hip; Bodyweight Version
Linear Velocity equals the distance traveled over time
Distance traveled: 1.13m time it took: .6sec
Linear velocity = 1.13m/.6sec= 1.88 meters per sec

7. Initial and Final Positions of Angular Velocity of Knee; Weighted Version

8. Calculations for angular velocity of the knee; Weighted Version
Angular Velocity equals Angular Displacement over time.
Angular Displacement equals final angle minus initial angle.
Final: 176 degrees - Initial: 53 degrees = 123 degrees
Converted to radians: 57.3 degrees in 1 radian 123/57.3= radians; rounded to nearest hundredth
Time it took: .8 sec
Angular Velocity= 2.15 radians/.8 sec= 2.69 radians per sec

9. Final and Initial Positions for Linear Velocity of the Hip; Weighted Version

10. Calculations for linear velocity of the hip; Weighted version
Linear Velocity equals the distance traveled over time
Distance traveled: 1.39 m Time it took: .8sec
Linear Velocity= 1.39 m/.8sec= 1.74 meters per sec

11. Results and Conclusion
Angular Velocity for the knee angle; bodyweight version: 2.88 radians per sec
Linear Velocity for hip angle; bodyweight version: 1.88 meters per sec
Angular velocity for knee angle; weighted version: 2.69 radians per sec
Linear velocity for hip angle; weighted version: 1.74 meters per sec
Video recorder man reported I jumped 3 to 4 inches with weight and 5 to 6 inches without weight
Because of my results, my hypothesis was proven correct. Measurements for bodyweight hip thruster was greater than weighted hip thruster causing myself to jump higher.
