A student wants to know if the effect of gravity is the same on all objects. She follows these steps:

Question

Drop a 5-gram ball, a 10-gram ball, and a 12-gram ball from a height of 10 meters.
Record how long it takes for each object to hit the ground.
?
Which step should be next?

(1 point)
Responses

Perform a second trial.
Perform a second trial.

Measure the mass of the balls again.
Measure the mass of the balls again.

Drop the balls from a different height.

Answer 1

The most appropriate next step is to perform a second trial.

Repeating the experiment helps to ensure that the results are consistent and reduces the impact of any anomalies or errors from the first trial. Measuring the mass of the balls again is unnecessary since the mass should remain the same, and dropping the balls from a different height would change the conditions of the experiment and not allow for a direct comparison of the effects of gravity on the different balls.
