<span>The heliocentric model of the universe was proposed by Nicolaus Copernicus. There are numerous scientist in ancient times who try to explain what happens in the universe. He may not be the first one who proposed that what astronomical body is the center of the universe. However, he stated that the center of the universe was the sun, not the earth. And the earth revolves around it. It is in his book on the Revolutions of the Heavenly Bodies. It was only published as he lay in his deathbed. </span>

the video identifies the force pair produced when an apple falls through the air. which force belongs in a free-body diagram of
trapecia [35]

The free-body diagram of an apple falling through the air has weight of the apple pointing downwards and the air-resistance on the apple acting upwards.

When an object falls from up to the ground, the object falls under in the influence of acceleration due to gravity.

The vertical component of the force on the apple as it falls trough the air is given as;

∑Fy = 0

Fₙ - W = 0

Fₙ = W

where;

  • <em>Fₙ is the frictional force on the apple acting upwards</em>
  • <em>W is the weight of the apple acting downwards</em>

The free-body diagram of the apple is represented as follows;

                                         ↑ Fₙ

                                         Ο

                                         ↓ W

Thus, the free-body diagram of an apple falling through the air has weight of the apple pointing downwards and the air-resistance on the apple acting upwards.

7. Why does increasing the mass of an egg increase the chance that it will be damaged in a drop?​
12345 [234]
Because if you increase the surface area of such a fragile object there is more space and in turn more of a chance for the object (in this case the egg) to be damaged.
