Question

investigating gravity quick check
a team of students performs an experiment to test the effect of gravity on different objects with the same mass. they measure how long it takes the objects to fall from the top of the schools bleachers. how can they insure they get accurate data? (1 point)
by dropping all the objects at once
by repeating the experiment several times
by using a high - tech stopwatch
by dropping the objects in random order

Explanation:

Repeating an experiment several times helps reduce the impact of random errors. Each repetition provides more data points, and averaging the results or looking for consistent trends gives a more accurate picture of the true effect (in this case, the effect of gravity on the objects' fall times). Dropping all objects at once could lead to visual confusion in measuring fall times. Using a high - tech stopwatch might not be necessary if basic stopwatches are used correctly and consistently. Dropping objects in random order doesn't directly address the accuracy of the data as much as repetition does.

Answer:

by repeating the experiment several times
