weight ( ) 1. The force with which an object near the Earth or another celestial body is attracted toward the center of the body by gravity. An object’s weight depends on its mass (the amount of matter it consists of) and the strength of the gravitational pull .
What 3 things does weight depend on?
The weight of any object is affected by three factors which are the object’s mass, the planet (the place) where the object exists, the distance between the object and the center of the planet .
What does weight depend upon?
Weight is the vertical force exerted by a mass as a result of gravity . Weight can also be defined as the strength of the gravitational pull on the object; that is, how heavy it is. Weight is dependent on gravity.
Why is weight in kg?
Since there is no practical easy way to measure mass, in everyday life we use the kilogram as a unit of weight assuming that the gravitational field is fairly constant around earth . However scales have to be calibrated locally to compensate the slight gravitational field variation in different places.
Can weight be negative physics?
Normal force is defined as the force that a surface exerts on an object. If the object is at rest, net force on the object is equal to zero; therefore, the downward force (weight) must be equal to the upward force (normal force). Since weight acts in the downward direction it will be negative .
Does weight depend on height?
Your ideal weight depends on a number of different factors, including: height . sex . fat and muscle composition .
What is the ideal weight for 5 feet female in KG?
Ideal body weight (men) = 50 kg + 1.9 kg for every inch above 5 feet. Ideal body weight (women) = 49 kg + 1.7 kg for every inch above 5 feet.
Is weight expressed in Newtons?
Weight is a measure ofthe force of gravity on a physical object and is measured in newtons .
Is it correct to say weight in kg?
Weight is the amount of force on an object due to gravity. ... To review, a person or an object has a mass that can be measured in kg. A person or an object that is on any celestial body with gravity has a weight that can be measured in N. It is completely incorrect to say that a person or an object has a weight in kg.
How can I calculate weight?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s 2 on Earth. The formula for calculating weight is F = m × 9.8 m/s 2 , where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
Is force equal to weight?
The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg . Since the weight is a force, its SI unit is the newton. Density is mass/volume.
What is the weight in physics?
Weight is a force acting on that matter . ... In physics, the term weight has a specific meaning – which is the force that acts on a mass due to gravity . Weight is measured in newtons. Mass is measured in kilograms. The mass of a given object is the same everywhere, but its weight can change.
Can weight be negative Newtons?
It can happen when the pilot “pushes on the stick” and dives. That’s this bold text that caught my attention. I learned in high school that the weight of an object equals its mass in kg times the acceleration of gravity in N/kg. An object mass cannot be negative and AFAIK, neither does the acceleration of gravity.
What is the perfect weight for my height?
| Height Weight | 5ft (60′′) 97 to 123 lbs . 153 to 199 lbs. | 5ft 1′′ (61′′) 100 to 127 lbs. 158 to 206 lbs. | 5ft 2′′ (62′′) 104 to 131 lbs. 164 to 213 lbs. | 5ft 3′′ (63′′) 107 to 135 lbs. 169 to 220 lbs. |

Can losing weight make you shorter?
Yep: height loss . Gaining weight on its own isn’t going to make you shrink. But if your weight causes complications that compromise the health of your bones, you may develop conditions that lose you a few inches.
