Best Answer

Scales are intended to measure some downward force acting on the scale, which is the weight of the object placed on the scale to be weighed, but it is also true that the downward force is necessarily balanced by an equal and opposite upward force, otherwise the scale would be forced downward (which would be very awkward since it would break through the floor and create quite a mess).

Q: A weight reading on a scale shows the upward force exerted by the scale?

Weight of the elevator = 1000kg x -9.8m/s2 = -9800N Upward force acting on the elevator = 1000kg x 2m/s2 = 2000N Net force = upward force - weight of elevator = 2000N - (-9800N) = 11800N

A spring force scale measures the downward pull on a spring exerted by a force, usually gravity acting on a weight.

Kilogram is the unit of MassNewton is the unit of ForceSince weight is a force, the SI unit of weight is the Newton1 kg is 9.8 Newtons of force being exerted on the earth's surface.

In mechanics, the force exerted upwards by the surface that a body sits on is equal and opposite to the force exerted downwards by that body and is referred to as the Ground Reaction Force (GRF) or simply Reaction.

It is a force which acts in the upward direction.

The upward force exerted by fluids is called buoyancy. It is dependent on the weight of the object in question.

The force is called buoyant force and it is equal to the weight of the fluid displaced by the object.

The force is exactly equal to your weight.

The weight reading on a scale measures the downward force exerted by an object due to gravity. The scale registers the force required to support the object's mass against the pull of gravity, which is then displayed as the weight of the object.

The upward force exerted on an object in a fluid is buoyancy.

upward acting force exerted by a fluid , that opposes an object's weight

Buoyancy is an upward thrust or force exerted by a fluid , that opposes an object's weight.

Buoyant force is the upward force exerted by a fluid (such as water or air) on an object submerged in it. It is equal to the weight of the fluid displaced by the object and acts in the opposite direction to gravity, helping objects float.

Buoyancy, which is an upward acting force exerted by a fluid , that opposes an object's weight.

buoyancy is the upward force that keeps things afloat. The net upward buoyancy force is equal to the magnitude of the weight of fluid displaced by the body. This force enables the object to float or at least seem lighter

Because your feet are not accelerating, the force exerted by the floor upon your feet must be exactly the same as the force exerted by your feet on the floor. If you are standing, the amount of force exerted by your feet, and thus the amount of force exerted by the floor, is equivalent to your weight.

Buoyancy is an upward acting force. It is caused by fluid preassure which opposes an objects weight ( their gravitational pull downwards ).
