Hello!
We have the following data:
KE (Kinetic Energy) = ? (in Joule)
m (mass) = 0.5 Kg
v (speed) = 10 m/s
<span>Formula to calculate kinetic energy:
</span>

Solving:
</span>





I hope this helps! =)
Your variables would be varied temperature while your constants should be everything else (water, soil, proximity). Therefore, you can test for one variable (temperature difference) without muddling the results
