3. Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity
Analyze results
What patterns do you notice in the time (t) column?
What patterns do you notice in the position (x) column?
What patterns do you notice in the speed (v) column?

4. Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity
Draw conclusions
Was the ball moving at a constant speed or was it accelerating?
How can you tell?
What caused the ball to accelerate?

5. Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity
Draw conclusions
What was the major source of error in our experiment? (What made the data so hard to collect?)
Why didn’t we use the frame when the ball was at 50 cm?

Reflect on gravity
Gravity is an attractive force that acts between any two objects.
What are the two objects attracting and pulling to make the ball fall?

7. Gravity and Kinetic Energy Course, 1.3: Acceleration of Gravity
Reflect on gravity
The force of gravity caused the ball to accelerate. The force of gravity is constant. It has been closely studied and can be measured and calculated.

Change units to meters
Acceleration of gravity on Earth is represented by the symbol g. Scientists typically use g in units of meter per second squared (m/s2), but you measured in centimeters. 100 cm = 1 m so divide cm/s2 by 100 to get m/s2
