What happens to the kinetic energy of a snowball as it rolls across the lawn and gains mass?

**Science/math**

Newtons second law of motion states that F =MA Force equals mass multiplied by acceleration. Mass is the constant. It does not change. What is the independent and dependent variable? I put force is independent and acceleration is dependent. Is that right?

**Math-Sorry I had a mistake in the first problem.**

Please check my work: Label the dependent and independent variable. 1. Time spent studying and Score on a test 2. If a scientist conducts an experiment to test the theory that a vitamin could extend a person's life expectancy. What are the dependent and independent ...
