What is the net force of an apple that weights 1N when you hold it at rest above your head?
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 identify all the forces acting on the apple and their reaction forces?
As its distance from the earths mass centre alters very little during the fall, the force between it and the earth essentially remains the same. During the fall the earth and the apple accelerate toward each other. acceleration = force / mass, so the earths acceleration is incredibly small and the distance moved also.
How much work is done if you hold a 50 N barbell over your head for 5 minutes?
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.
Why isn't work done as you hold a book motionless over your head?
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.
How did the apple fall out of the tree and onto Isaac newtons head?
This has actually been greatly speculated on, as Newton, according to his own memoirs never said he was hit in the head by an apple, but only saw that apples fell while in the garden. He then used it as an example to explain his hypothesis and then theory to others. "The weather being warm, we went into the garden and drank tea, under shade of some apple-trees, only he and myself. Amidst other discourses, he told me, he was just in the same situation, as when formerly, the notion of gravitation came into his mind. It was occasioned by the fall of an apple, as he sat in contemplative mood. Why should that apple always descend perpendicularly to the ground, thought he to himself. Why should it not go sideways or upwards, but constantly to the earth's centre." -From Memoirs of Sir Isaac Newton's Life pp19-20. It was pointed out on one forum that it was actually a gentleman by the name of John Conduitt, that had the 'gravity' revelation after his wife (Newtons niece), was struck on the head by an apple.
You hold an apple over your head Identify all the forces acting on the apple and their reaction forces when you drop the apple identify all the forces acting on it as it falls and the corresponding?
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.
What color was the apple that fell on isaac newtons head?
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.

What words means to hold it over their head?
