Analyzing acceleration expermient

Analyzing and studying the acceleration, speed and velocity of a marble as a Go-cart in different contexts such as changes in velocity and direction.

0.    Hypothesis: When a marble advance through several points, its velocity decrease, and when a marble changes direction by hitting another object, it decelerates.

1.    Objectives.

__Analyze acceleration in different contexts, such as velocity and direction.

__See if an object accelerates or not if hits something.

__Know how to apply the theory of acceleration in the daily life.

__Learn how acceleration can affect effective and quality of an object.

2.    Materials and Reactives.

- Marble

- Chronometer (Timer)

- A channel or tunnel-like surface.

- Measuring Tape.

- Paper and pen. (To take notes and mark distances)

3.    Procedure.

a.     Measure with measuring tape a distance (optional) in the channel-surface.

b.     Mark the limits and distances.

c.      Throw the marble and start recording the time to see its velocity

d.     Now, mark some distances and get the time when the marble reach it to see its acceleration or deceleration.

e.     Record these results and make some calculations.

f.       Now repeat these steps throwing the marble faster or slower.

g.     Now, in a wall (it has to be in the floor) throw the marble (no in right angle) to see a change in direction.

h.     Take the time it takes the marble to reach the wall and a certain point, to see if it accelerates or decelerates.

i.       Record these observations and make some calculations.

4.    Observations and Results.

·           In every time we throw a marble in any distance, as it progresses it lose velocity and goes slower.

·           When a marble hits another object and changes direction, it goes slower or even stops.

·           If you throw the marble with more impulse it will go faster and last farther or even over pass the solid limit. (Vice versa)

·           Between more distance there is, less velocity the marble will have as it progresses. (Vice versa)

5.    Conclusions

The impulse and distance affects velocity and acceleration of an object.
