A student wants to know if the fact is gravity is the same on all objects. She follows the steps.

1. Drop a five grand bar, a 10 g ball, And a 12 g ball from a height of 10 m
2. Record how long it takes for each object to hit the ground
3. ?
Which step should be next?
A. Drop the bars from a different height
B. Perform a second trail
C. Choose new balls
D. Measure the mass of the balls again

B. Perform a second trial

B. Perform a second trial

The next step in this experiment should be to perform a second trial. This is an important step to ensure accuracy and consistency in the data collected. By repeating the experiment, the student can verify that the results obtained are reliable and representative of the actual situation. This will help in drawing a more conclusive answer to the question of whether gravity is the same on all objects. Therefore, the correct answer is B. Perform a second trial.
