Fill in the blanks and complete the following paragraph . (words given: upward, friction,negligible,downward , gravitational , buoyance , very large, electric) When a body falls in air, there are three forces acting on the body : (1) the gravitational force due to the earth, acting........(2) the force of ........ due to air, acting .....(3) the force due to...... with air, acting in the direction oppositeto that of the velocity of the body. Under certain conditions, the force of buoyancy due to air and friction with air can be....... compared to the.......force of the earth. In that case (near the earth's surface) the body falls with almost uniform acceleration (g). Whenever a body moves under the influence of the force of gravity alone, it is said to be falling freely. Strictly speaking, this is true only if the body falls in vaccum.
