Answer 1

#1

We get the energy by the foods we take and respiration+ digestion plays key role in transformation

#2

• Faster the speed faster the Kinetic energy
• Slower the speed slower the Kinetic energy

This is because KE=1/2mv²

Answer 2

First one is by the food we eat, we get fuel to be able to move and do work.

Second one is, the effect of speed on kinetic energy is the faster or slower something is going at, the more or less movement needed.
