What is a simple definition of weight?
noun. a measure of the heaviness of an object; the amount anything weighs. physics the vertical force experienced by a mass as a result of gravitation. It equals the mass of the body multiplied by the acceleration of free fall.
What is weight in science definition?
Scientists, however, have a specific definition for weight; they use it to describe the effect of gravity on an object. Weight is a measure of the gravitational force with which an object is drawn to the center of a massive second object, such as Earth or the Moon.
What is the example of weight?
Weight is how heavy something is or how much mass it has. An example of weight is when a person is 100 pounds. A measure of the heaviness of an object. A contest to guess the weight of a pig.
What is the meaning of weight by weight?
It equals the mass of the body multiplied by the acceleration of free fall. Its units are units of force (such as newtons or poundals) but it is often given as a mass unit (kilogram or pound). Symbol: W. 3. (Units) a system of units used to express the weight of a substance: troy weight.
What is a weight in physics?
Weight is a force acting on that matter . Mass resists any change in the motion of objects. 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.
What is weight in physics class 9?
The weight of a body is the force with which it is attracted towards the centre of the earth. The force of attraction of earth on a body is called as weight. … The weight of an object on moon is the force with which the moon attracts the earth.
How do you write weight?
There are two common abbreviations of weight: wt.and wgt.
What is weight gravity?
The weight of an object is defined as the force of gravity on the object and may be calculated as the mass times the acceleration of gravity, w = mg. … You can view the weight as a measure of the mass in kg times the intensity of the gravity field, 9.8 Newtons/kg under standard conditions.
What is meant by weight class 6?
unit. Solution: The weight of a body is the force of gravity on it. The weight of a body is not constant,it changes from place to place. The S.I unit of weight is newton (N).
What does standard weight mean?

Earth/Mass
Do heavier objects fall faster?
Answer 1: Heavy objects fall at the same rate (or speed) as light ones. The acceleration due to gravity is about 10 m/s2 everywhere around earth, so all objects experience the same acceleration when they fall.
How do we measure weight?
Measuring Weight Accurately At Home
- Use a digital scale. …
- Have the child or teen remove shoes and heavy clothing, such as sweaters.
- Have the child or teen stand with both feet in the center of the scale.
- Record the weight to the nearest decimal fraction (for example, 55.5 pounds or 25.1 kilograms).

What is the heaviest planet?
Jupiter
Jupiter is the largest planet in our Solar System with the most mass. Because of Jupiter’s mass, you would weigh more on that planet than on any other one in our Solar System. If you weighed 68 kg on Earth then you would weigh 160.7 kg on Jupiter, over twice your normal weight.
What is the heaviest thing on Earth?

How long will the earth last?
By that point, all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
