PART 1: READING - The cloud should contain the MAIN IDEA of each paragraph. Imagine you're at lunch. Your nose smells pizza. Your
legs move over to where hot lunch is being served. You have
to balance the food and your milk in your hands, look
around for a free seat, and then sit down. This may seem
simple, many different parts of your body have to work
together to make all of that happen. To make sure your
body can work correctly, even when it does many things at
once, your body must be carefully organized.

step-by-step explanation:

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
