Mini Challenge

Construction of a Free Fall Experiment

Students will construct a simple experiment to measure the fall time of an object from a certain height and calculate the final velocity and distance traveled.

Instructions

1. Divide the class into small groups.
2. Distribute the necessary materials: stopwatches, measuring tapes, objects of different masses (such as spheres) and recording sheets.
3. Guide students to choose a fixed height (for example, 2 meters) from which they will drop the objects.
4. Ask the groups to measure the time each object takes to hit the ground, using stopwatches.
5. Guide students to record the measured times and repeat the experiment several times to obtain an average.
6. Using the formula for uniformly accelerated motion (h = 1/2 gt²), ask them to calculate the final velocity and the distance traveled.
7. Request that each group present their results and discuss possible variables that may have influenced the experiments, such as air resistance.

Objective: The objective of this activity is to allow students to practically apply the concepts of vertical motion by making measurements and calculations involving time, distance, and velocity. This also promotes teamwork and problem-solving skills.
