How is it possible you can feel heat from the sun?

there are three ways by which we can transfer heat from one place to other

1. Conduction

In this method of heat transfer heat can be transferred from one place to other without actual movement of medium molecules. This is possible in solid conducting mediums

2. Convection

Here heat energy is carried away along with the medium molecules where medium molecules can move from one place to other while heat is transferred. It is possible in liquid and gas but not possible in solids

3. Radiation

In this mode of heat transfer we do not require any medium and here heat transferred by electromagnetic waves

So we can feel heat from sun in form of electromagnetic waves and it is the fastest way to transfer the heat also it do not require any medium

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.
