What else can I help you with?
An empty office chair is at rest on the floor Consider the following forces Gravity Upward force exerted by the floor A net downward force exerted by air What forces are acting on the office chair?
The forces acting on the office chair are gravity pulling it downwards and the upward force exerted by the floor counteracting gravity to keep the chair at rest. The net downward force exerted by air will have a negligible effect and can be ignored in this scenario.
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
Inertia will not be affected when this type of force is zero.?
Inertia will not be affected when "net" or "net force" is zero.
What Combination of all of the force acting on an object?
The net force acting on an object is the combination of all individual forces acting on it. It is the vector sum of all forces, taking into account their magnitudes and directions. The net force determines the acceleration of the object according to Newton's second law of motion.
When a person sits on a chair what are the action and reaction?
When a person is sitting still in a chair, the action and reaction forces meet along his bottom. The 'action' is directed downward and is the person's weight, the result of the gravitational attraction between the Earth's mass and the person's mass. The 'reaction' is directed upward, and is the force developed in the structural materials of the floor and the chair. Since the action and reaction forces are equal and opposite, the net force on the person's bottom is zero, and he does not accelerate vertically.
Is it ture or false that The net force acting on you when you sit still in a chair is zero?
Yes, it is true that the net force acting on you when you sit still in a chair is zero. This is because the force due to gravity pulling you downwards is balanced by the normal force exerted by the chair pushing you upwards, resulting in no acceleration in any direction.
Why doesn't the force you exert when sitting on a chair cause the chair to move?
because the floor exerts the same amount of force which means the net force is balanced causing it not to move
An empty office chair is at rest on the floor Consider the following forces Gravity Upward force exerted by the floor A net downward force exerted by air What forces are acting on the office chair?
The forces acting on the office chair are gravity pulling it downwards and the upward force exerted by the floor counteracting gravity to keep the chair at rest. The net downward force exerted by air will have a negligible effect and can be ignored in this scenario.
When you sit on a chair a resultant force on you is?
The Answer is (A) - Zero Explanation: When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body. There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces.
What can you say about an object at rest pulled in opposite directions by unequal forces?
An object at rest pulled in opposite directions by unequal forces will start to move in the direction of the net force. For example, if I have a chair, and I'm pushing with 10 newtons to the right, and my sister is pushing 5 newtons to the left, the net force is 5 newtons to the right. Therefore, I win, and the chair moves to the right, in the direction of the net force.
When you sit in a chair what force does it exert against you?
A force exactly equal to the weight of your posterior against the chair. You know positively that the forces there must exactly cancel and add to zero, otherwise a net, non-zero force would be present, and your butt would accelerate.
What amount of work is done on a chair that is pushed 89 m across a floor by a horizontal 30-N net force?
The work done on the chair can be calculated using the formula: work = force x distance x cos(theta). Given a net force of 30 N and a distance of 89 m, the work done on the chair is 30 N x 89 m x cos(0°) = 2670 Joules.
Why is it useful to know the net force?
You must know the the direction so then you know if you either subtract or add. For example , if the the direction of the force is in opposite then you would have to subract each net force.
Inertia will not be affected when this type of force is zero.?
Inertia will not be affected when "net" or "net force" is zero.
What is the net force for 70N and 45N?
To find the net force, subtract the smaller force from the larger force. Net force = 70N - 45N = 25N. Therefore, the net force is 25 Newtons.
Why is UseFul know to the net force?
If you know the net force on an object, you can determin the effect of the net force on the objects motion. (I got this answer from my text book. Therefore, it's right)
Do all action-reaction forces produce motion?
Some do and some don't. In the case of someone sitting on a chair, they exert a downward force on the chair due to their weight. The chair exerts an equal and opposite reaction force on them but, since this upward force acting on the person is equal to their weight, the net force is zero and the person does not accelerate. However, consider now if the person pushed themselves up off the chair with their hands. They are now exerting an additional force on the chair with their arms along with the force due to their weight. The chair will exert a reaction force on the person that is equal and opposite to the combined downward force due to the person's weight and their arms pushing. Since it is equal to the weight plus the pushing force of the arms, it will be greater than the downward force on the person due to their weight and a net upward force will be produced, accelerating the person upwards.
