Answer» falling of an apple from a tree is an example of "GRAVITY" Answer:b) gravityExplanation: Gravity causes theappletofalltowards the earth's center of mass and friction between theappleand the molecules of the atmosphere acts to slow theapple. falling of an apple from a tree is an example of gravity falling an apple from a tree is an example of gravity (by newton) falling of an apple from tree example of gravity The right answer is gravity the answer is:_falling an apple🍎 from a tree🌲 is an example of🛶 gravity by Newton✔️ The answer is :_(B) Gravity Newton's Third Law Action and Reaction Forces Physical Science 112: Written by H. Tahsiri An apple in free fall accelerates toward the Earth with a free fall acceleration, g.The force of the apple on the Earth also causes the Earth to accelerate toward the falling apple.By Newton's Third Law, the force of the Earth on the apple is exactly equal and opposite to the force of the apple on the Earth.By Newton,s Second law, the force of the Earth on the apple is equal to the mass of the apple times g , the accelerations due to gravity. And, the force of the the apple on the Earth is equal to the mass of the Earth times the acceleration of the Earth toward the apple.In conclusion, the magnitude of the forces are equal,or F ( apple on the Earth) = F( the Earth on the apple)or M( mass of the earth) xa( the acceleration of the earth toward the apple) =m(mass of the apple) xg( the acceleration of the apple toward the Earth)or a=(m/M)g where g= 9.8 m/s/s This ratio of the masses is about 1/10^24.The Earth's acceleration due to the pull of the apple is so small, it is impossible to detect. |
