Classify the waves as being mechanical or electromagnetic. microwave ocean wave seismic wave radio wave

Micro waves and radio waves are electromagnetic waves while ocean wave  and seismic wave are mechanical waves.

Explanation:

Electromagnetic waves do not require a medium for propagation. They can travel along vacuum just like they travel through matter.

Further examples of electromagnetic waves are x rays, infrared waves etc.

Spectrum of electromagnetic waves in the increasing order of frequency is radio waves, microwaves, infrared waves, visible light, ultraviolet, x ray, gamma ray.

Mechanical waves require a medium for propagation. Thus they cannot travel through a vacuum.

Sound wave is an example of mechanical wave.

i'm thinking more like energy

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.
