What is an example of mass and weight?
The mass of an object will never change, but the weight of an item can change based on its location.
For example, you may weigh 100 pounds on Earth, but in outer space you would be weightless.
However, you will always have the same mass on Earth as you have in outer space..
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/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is weight 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. W=m*g. S.I. unit of weight is Newton or kg m/s2. Weight of 1 kg mass is 9.8 Newton.
Why is the weight of an object on the moon?
The mass of moon is 1/100 times and its radius 1/4 times that of earth. As a result, the gravitational attraction on the moon is about one sixth when compared to earth. Hence, the weight of an object on the moon is 1/6th its weight on the earth.
What is difference between mass and weight Brainly?
Answer Expert Verified Hey! Mass is the total matter contained in a body while weight is the force with which an object is attracted towards the earth.
What is a healthy weight?
A result between 18.5 and 24.9 means you’re in the “normal” weight range for your height. If your result is under 18.5, you’re considered underweight. Between 25 and 29.9 means you’re considered overweight. And if your number is 30 to 35 or more, you’re considered obese.
What do you mean by free fall?
In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. … A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement.
What is SI unit of weight?
The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.
What are 3 differences between mass and weight?
It is the measure of the amount of matter present a body. It refers to the measure of the amount of force that acts on mass because of the pull of gravity. Mass is the measure of inertia. Weigh is the measure of force.
What do you mean by free fall class 9?
The falling of a body from a height towards the earth under gravitational force is called Free fall. Such a body is called freely falling body. … The acceleration of an object falling freely towards the earth does not depend on mass of object. During free fall,heavier as well as light objects accelerate at same rate.
What is the force of 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.
What is my ideal weight in kg?
It gave the ideal weight according to height and the following formulae were used in traditional weight calculators: 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.

What is the difference between mass and weight class 9?
The difference between mass and weight is that mass is the amount of matter in a material, while weight is a measure of how the force of gravity acts upon that mass. Mass is the measure of the amount of matter in a body. … Weight usually is denoted by W. Weight is mass multiplied by the acceleration of gravity (g).
