Question

procedure — part ii

1. now use the meterstick to measure a 6 m straight path along the floor. place a mark with masking tape at 0 m, 3 m, and 6 m.
2. look at the graph below. decide what type of motion occurs during each 5 - second period.
3. try to walk along your path according to the motion shown on the graph. have another student time your walk with a stopwatch. switch roles and repeat this step. record your observations below.
4. follow your teachers instructions for proper cleanup.

data and observations

Explanation:

Step1: Analyze 0 - 5 s

The distance increases steadily from 0 m to 3 m. This is uniform - motion (constant speed).

Step2: Analyze 5 - 10 s

The distance remains at 3 m. The object is at rest.

Step3: Analyze 10 - 15 s

The distance increases from 3 m to 6 m. This is uniform - motion (constant speed).

Step4: Analyze 15 - 20 s

The distance remains at 6 m. The object is at rest.

Step5: Analyze 20 - 25 s

The distance decreases from 6 m to 3 m. This is uniform - motion (constant speed) in the opposite direction.

Step6: Analyze 25 - 30 s

The distance decreases from 3 m to 0 m. This is uniform - motion (constant speed) in the opposite direction.

Answer:

0 - 5 s: Uniform motion (constant speed)
5 - 10 s: At rest
10 - 15 s: Uniform motion (constant speed)
15 - 20 s: At rest
20 - 25 s: Uniform motion (constant speed) in the opposite direction
25 - 30 s: Uniform motion (constant speed) in the opposite direction
