Answer:
Q1: c
Q2: a
Explanation:
you can tell the factors by looking at the formulas for kinetic and potential energy
for question 1 look at the formula for kinetic energy
the variables needed in order to calculate an object's kinetic energy are mass and velocity.
hence, when mass and velocity changes, kinetic energy changes, showing that mass and velocity are the factors affecting kinetic energy
same thing for the second question
as g (acceleration due to gravity) is considered constant (10 ) it will not be considered as a factor
and thus, the factors affecting potential energy are mass and height
