What is the force of an apple falling from a tree?
The unit of force is the newton (N) named after Sir Isaac Newton (1642 – 1727). He observed apples falling from a tree and realised that the force produced by a falling apple is equal to its mass times the earth’s gravitational pull.
What is the mass of an object if a net force of 8.0 N causes it to accelerate at 1.1 m s?
m= 8/1.1 = 7.27 Kg.
Which formula is used to calculate the mass of an object if the force and acceleration are known?
It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.
Is an apple falling from a tree an unbalanced force?
When an object is moving with changing speed, the net force on it is unbalanced. For example, when an apple falls from the tree an unbalanced force equal to its weight is acting on the apple.
What makes an apple fall?
Other reasons for fruit fall are a bit more sinister. Attack by either pests or disease can result in fruit drop. Speaking of pollinators, another reason an apple tree might shed fruit is if there is inadequate pollination during bloom time. Keep pollinators within 50 feet (15 m.)

What is the true mass of an apple?
The average apple is between 70 and 100 grams or 0.33 pound or 0.7 and 1N.
What happens to an apple that falls freely?
When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls. When the apple hits the ground, kinetic energy is transformed into heat energy.
What are the forces that cause an apple to fall?
There would be two forces acting upon the apple assuming that it is falling in an atmosphere: gravity and friction. Gravity causes the apple to fall towards the earth’s center of mass and friction between the apple and the molecules of the atmosphere acts to slow the apple.
What was the force of gravity on the Apple?
In Einstein’s theory those minor forces are the same, but there is no force of gravity. The apple had the force of its stem acting on it which was preventing it from following the natural straight path thru spacetime. Since the stem broke the apple proceeds along that geodesic path which intersects the ground below it.
What did Isaac Newton say about the fall of apples?
“He showed that the force that makes the apple fall and that holds us on the ground is the same as the force that keeps the moon and planets in their orbits,” said Martin Rees, a former president of Britain’s Royal Society, the United Kingdom’s national academy of science, which was once headed by Newton himself.
