Astudent is testing the kinematic equations for uniformly accelerated motion by measuring the time it takes for light-weight plastic balls to fall to the floor from a height of 3 m in the lab. the student predicts the time to fall using g as 9.80 m/s2 but finds the measured time to be 35% greater. which of the following is the most likely cause of the large percent error?
(a) the acceleration due to gravity is 70% greater than 9.80 m/s2 at this location.(b) the acceleration due to gravity is 70% less than 9.80 m/s2 at this location.(c) air resistance increases the downward acceleration.(d) the acceleration of the plastic balls is not uniform.(e) the plastic balls are not truly spherical.

The variables for this experiment include mass, volume and the materials in the various balls, as well as their densities. in part iii, you will be investigating the questionable baseball. use the drop-down menus to complete the sentences and identify the independent and dependent variables. in part iii, the independent variable, the one that is intentionally manipulated, is . in part iii, the dependent variable, the one that you measure the response in, is
