# Question: What is the net force on an apple that weighs 1 n when you hold it at rest above your head?

## What is the net force on a 1 N Apple when you hold it at rest?

The apple is held at rest, therefore, the net force is 0N. When you drop the apple the net force on the apple is just due to its weight W = 1N.

## When an apple that weighs 1 N is dropped and freely falls the net force on the apple is?

when an apple that weighs 1N is dropped and freely falls, the net force on the apple is. 1N.

## When you hold an apple above your head how many forces act on the apple?

(a) Two force pairs act; Earth’s pull on the apple (action), and the apple’s pull on the Earth (reaction). Hand pushes apple upward (action), and apple pushes hand downward (reaction).

## How is net force calculated?

FN is the force acting on a body. When the body is at rest, the net force formula is given by, FNet = Fa + Fg.

## What is the net force acting on a 1 kg ball in free fall?

The net force acting on 1-kg ball in free fall is 9.8 N.

## What is the net force of an object at rest?

The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero.

## When you push against a wall What pushes back?

According to Newton’s third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

## When the net force on an object is zero its acceleration?

Newton’s First Law can be seen to be the special case in the Second Law when F, the net force, is zero. When that happens, the acceleration a must also be zero. Since acceleration is given by the change of velocity divided by elapsed time, the velocity doesn’t change.

## What is the net force that acts on a 10n free falling object?

The ratio of force to mass for free falling objects is equal to the force of gravity ‘g’ which at the surface of the earth is equal to 9.8 m/s2. What is the net force that acts on a 10-N freely falling object? The net force acting on a 10 N free falling object is 100 N (98 N to be precise).

## Why does weight not affect acceleration?

“What are the factors that affect the acceleration due to gravity?” Mass does not affect the acceleration due to gravity in any measurable way. The two quantities are independent of one another. Light objects accelerate more slowly than heavy objects only when forces other than gravity are also at work.

## What force causes an apple to fall from a tree?

An apple hanging on a tree is acted upon by two basic forces: 1) the downward force exerted by the gravity force and, 2) the upward force exerted by the tree limb. The downward gravity force is also know as “weight“.

## What law is best described by inertia?

Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

## Do you add or subtract to find net force?

Net force is determined by adding up all of the individual forces on an object. For example, to determine the net force on an airplane, you would add up the lift, weight, thrust, and drag. If forces are in opposite directions, like lift and weight, then you subtract them.

## Can Net Force be negative?

Yes. Force can be negative. Suppose you apply a force but you aren’t able to move it in the direction you apply force, so logically you aren’t able to apply force in the desired direction but you are being overcome by the force applied the other object. So the net force you apply is negative.

## What is a balanced force?

Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force.
