Acceleration of Free Fall

Acceleration is a vector quantity. 

No matter what your initial velocity is, if the force causing this is removed, you will accelerate under free fall. 

All objects fall at the same rate, and the only force acting on you is your weight. 

'g' is 9.81m/s2 but this can vary on the Earth's surface.

1. Measure the displacement from an electromagnet to the trapdoor. 

2. Flip the switch to release the ball bearing from the electromagnet and set the timer. 

3. The ball will break the circuit when it hits the trap door, stopping the timer. Record t. 

4. Repeat this for three times to find the average, and do this for a range of heights. 

5. Draw a graph of s against t2 to find 1/2a from the equation s=1/2at2

TO INCREASE ACCURACY :

- Use a smaller and more dense ball to ignore air resistance. 

- Use a ruler with smaller…
