Here is a list of my labs.

1. Lab - Uniform Motion: In this lab, we walked in front of motion sensors to
create position vs. time and velocity vs. time graphs.

3. Activity - Lab Analysis Practice: In this activity, we used a string
and a ball to measure the relationship between force and velocity
in this setting.

4. Lab - Acceleration vs. Time: In this lab, we calculated the displacement
with time and made a graph which the slope is acceleration.

5. Activity - Vector Inspectors: In this activity, we did a simulation lab to
add vectors graphically to learn how to measure vectors.

6. Lab - Projectile Motion: In this lab, we measured the launch angles
and range, and found it's relation.

7. Lab - Newton's 2nd Law - In this lab, we added mass to the cart to find
it's relationship with acceleration.

8. Lab - Friction - In this lab, we changed the friction coefficients and
the mass of the block and/or gravitational field, followed by changing
the angle to find the actual ramp angle similar to the prediction.

9. Lab - Newton's Law of Gravity - In this lab, we determined what affects the
strength of gravity between 2 objects, explained Newton's third law, related
distance, mass, and gravity force.

10. Lab - Work - In this lab, we saw the relationship between the angle of the
ramp and the force of gravity, and the more the distance the lower the force.

11. Lab - Hooke's Law - In this lab, we found out the Spring Constant from
experimentation by finding out the force at different spring displacements.

12. Lab - Impulse - In this lab, we used a force sensor and a motion sensor
to find how velocity and force reacts to different types of springs.
The harder the spring the more impulse.

13. Lab - Collisions - In this lab, we tested different types of collisions,
Elastic and Inelastic, finding the momentum and kinetic energy in each,
and the relationship between total momentum and energy.

14. Lab - Period of Springs and Pendulums - In this lab, we found the
periods of oscillation with different masses and it is a square root
relationship.

15. Lab - Standing String Waves - In this lab, we found the relationship
between wavelength vs period (linear), and wave speed vs tension (inverse).

16. Lab - Speed of Sound - In this lab, we used lab data to calculate
the speed of sound from frequency and wavelength, and found the
relationship between them.

17. Lab - Torque - In this lab, we tested torque with the distance from
the pivot (less distance, more force required)and thedirection of the
meterstick, as well as the center of mass.
