A student designs an investigation to study the effect of gravity on objects on Earth. He will use the criteria shown. How can the student improve the investigation?
by measuring the circumference of the balls
by finding balls made from different materials
by using balls that are the same mass
by dropping the balls from the same height
1 answer
The student can improve the investigation by using balls of different masses in addition to using balls of the same mass. This will allow for a more comprehensive understanding of how gravity affects objects of varying weights. Additionally, the student could also consider measuring the diameter of the balls to see if there is any correlation between the size of the object and the effect of gravity. Finally, the student should ensure that all other variables are controlled for, such as the height from which the balls are dropped and the surface on which they land.
