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 the apple when you release it?
0N
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.
What is the force that you exert on the apple?
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 is normal force measured in?
That’s a normal force. In general, any reactive force caused by a surface is a normal force. Newtons (N). One newton is one kilogram times one metre divided by one second-squared.
When an apple that weighs 1 N is dropped and freely falls the net force on the apple is group of answer choices?
when an apple that weighs 1N is dropped and freely falls, the net force on the apple is. 1N.
What is the net force that acts on a 10 N freely 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).
When an apple that weighs 1N is dropped and freely falls the net force on the apple is?
How do you find the direction of the normal force?
So on a flat table (horizontal) normal force is vertical = object’s weight (mg). On an inclined ramp, angle of inclination α, the component of the objects weight perpendicular to the ramp will be mg cos α. This will be the magnitude of the normal force. The direction of the normal force will be α west of the vertical.
What are the forces felt by an apple?
Answer: The forces felt by the apple are the upward force exerted on it by the string (string tension) and its weight, i.e. the downward force from the Earth’s gravity. These two forces are not an action/reaction force pair in the sense of the 3rd law.
What happens to the net force when an apple is released?
The reaction force to the force the Earth exerts on the apple is the force the apple exerts back on the Earth. When the apple is released the support force disappears. The net force is no longer zero but equal to the force of gravity (the force the Earth exerts on the apple). The reaction force is the force the apple exerts on the Earth. Nice work!
How is the net force determined in physics?
Determining the Net Force. The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
What happens when you hold an apple above your head?
When you hold the apple above your head, the net force on the apple is zero. The apple is at rest. There are two forces acting on the apple. The support force (lets say the force of the hand acting on the apple) and the weight (the force of gravity which is the force the Earth exerts on the apple).
