The net force on the apple is 0 N because it is at rest, and the force of gravity pulling it downward (1 N) is balanced by the force you apply upwards when holding it at rest above your head.
When you hold an apple over your head, the forces acting on the apple are the force of gravity pulling it down and the force of your hand pushing it up. The reaction forces are the apple pushing down on your hand with an equal force to gravity and your hand pushing up on the apple with an equal force to counter gravity.
The work done is zero, because holding the barbell over your head does not involve moving it vertically. Work is only done when there is a displacement in the direction of the force being applied.
Work is the product of force and displacement in the direction of the force. When holding a book motionless over your head, the force applied is vertical while the displacement is zero. Therefore, no work is being done as there is no movement in the direction of the force.
The story of the apple falling on Isaac Newton's head is a well-known anecdote, though its accuracy is debated. It is said that while resting under an apple tree, Newton observed an apple falling and began contemplating the force of gravity that pulled it towards the Earth. This event is often cited as the inspiration behind his theory of universal gravitation.
When holding the apple over your head, the main force acting on the apple is the force of gravity pulling it downwards, with the reaction force being the apple exerting an equal force upwards on your hand. When you drop the apple, the only force acting on it is still gravity pulling it downwards, but now there is no reaction force as the apple is falling freely.
There is no historical record of the color of the apple that fell on Isaac Newton's head. The famous story about Newton's apple and the theory of gravity is a popular myth that has been passed down over the years.
Sir Isaac Newton in the 1660s :- he told the story of watching an apple fall from a tree and it has been embellished over the years to it hitting him on the head
you can try shooting an apple over their head
To hold something over one's head - to harp on someone about something they did (or didn't do); to remind continuously (especially regarding misstep or defeat). For example,"I broke my girlfriend's vase and she's been holding it over my head for 3 months, now."
Holding something over your head gives the mental image of holding it just out of reach so that you will pursue it.
Zeus's daugher,Athena grew out of his head and his head had an apple. The apple was like the stem and Athena was the flower growing out of it.
I Have No Freakn Idea ! :DDD
To hold up a plant and to whack people over the head with.
"Say Anything"

Yes. Zeus's daugher, Athina grew out of his head and his head had an apple. (The apple was like the stem and Athina was the flower growing out of it).
