The force exerted by the boy on the chair is equal to his weight, which is calculated as mass times gravity. At sea level, gravity is approximately 9.81 m/s^2. Therefore, the force exerted by a 50 kg boy on a chair at sea level is 50 kg * 9.81 m/s^2 = 490.5 N.

How much force a walking man exerts on the ground A A force greater than his weight B A force equal to his weight C A force less than his weight D A force not related to his weight?
B. A force equal to his weight. When a man is walking horizontally on a level surface, the force he applies to the ground is equal in magnitude to his weight in order to support his body and propel him forward.
What force acts against the gravitational force that is in the upward direction?
The force that acts against the gravitational force in the upward direction is typically the normal force. The normal force is the force that a surface exerts on an object in contact with it, pushing against the force of gravity.
The atmospheric pressure at sea level is about 1 105 Pa What is the force at sea level that air exerts on the top of a typical office desk 154 cm long and 78 cm wide?
To find the force air exerts on the desk, you need to multiply the atmospheric pressure by the area of the desk. First, convert the dimensions to meters (1.54 m long and 0.78 m wide), then calculate the area (1.54 m * 0.78 m = 1.204 m^2). Finally, multiply the area by the pressure to find the force (1.105 Pa * 1.204 m^2 = 1.33 N).
Does a vertical force do work on an object that is moving in horizontal direction?
No, a vertical force would not do work on an object moving horizontally because the force is being applied in a different direction from the object's motion. Work is only done when the force and the displacement are in the same direction.
What force is required to push an 600N object?
If the object is at rest, a force greater than 600N would be required to overcome static friction and start its motion. Once in motion, a force equal to 600N would be needed to keep the object moving at a constant velocity on a level surface, assuming there is no other resistance.
How much does a kilogram weigh?
A kilogram weighs a kilogram or, exerts a force of around 9.8 Newtons on Earth at ground level.

What causes a geri-chair to flip over backwards?
A geriatric chair, also known as a Geri chair may flip over backwards if they are not leveled out right with weight. By this I mean if the weight sitting in the chair is not leveled out forward to backward and the position of the chair placed where the persons feet level out their top body, the chair may flip over.
Does atmospheric pressure still exert a force on you when you are under water?
Atmospheric pressure exerts more force on you if you are deeper than 10 meters. At 10m below sea level the atmospheric pressure is double that of on land and it increase with every 10 metres that you descend

Why does pressure increase as depth increase?
Fluid pressure increases with depth because the weight of the liquid on top of the measuring level exerts force downwards. It is the same effect as piling up 10 plates because the one below gets all the pressure.
