What is my mass if my weight is 70 kg?

What is my mass if my weight is 70 kg?

The weighing scale has effectively already divided the force by gravity (9.8 m/s^2) and it is displaying the result, which is your mass, of 57 kg. You should not divide by gravity again.

What is the weight of a 70 kg man in Newtons?

On Earth, a 70 kg person will weigh 70 kg times 9.8 m/s^2 = 686 kgm/s^2, or 686 Newtons.

How do you calculate the mass of a person?

To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons.

How much does a 70 kg astronaut weigh in space far from any celestial body?

How much does a 70-kg astronaut weight in space, far from any celestial body? What is her mass at this location? The astronaut is truly weightless in the location described, because there is no large body (planet or star) nearby to exert a gravitational force. Her mass is 70 kg regardless of where she is located.

What is the weight of a man whose mass is 70 kg?

Weight is mass times gravity (W = m x g). On Earth, a 70 kg person will weigh 70 kg times 9.8 m/s^2 = 686 kgm/s^2, or 686 Newtons.

What is the weight of a 70 kg man at standard condition?

A “standard man” was described as weighing 70 kg (154 pounds) and being 170 cm tall (5′7″). This individual would end up with a calculated body mass index (BMI) of 24.1 kg/m2.

How do you calculate weight from mass?

  1. 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.
  2. 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 the mass of a human?

The University of Arkansas defines the average all around body weight of an adult to be roughly 70 kilograms or 154 pounds (1pound is about 0.4539 kg)….Mass of an Adult.

Quantity Approx. value
Height 1.72 m
Mass 70 kg
Muscle mass 30 kg

How do you find the mass of an object with acceleration?

For instance, if the object accelerates over the course of 5 seconds: 30 ÷ 5 = 6 m/s². Divide the force acting on the body by this acceleration. If, for instance, a force of 12,000 Newtons acts on it: 12,000 ÷ 6 = 2,000. This is the object’s mass, measured in kilograms.

How do you calculate weight in space?

To calculate weight due to gravity, you would use Newton’s law of universal gravitation. The force of gravity (F) is equal to the gravitational constant (G) times the mass of one object (m1) times the mass of a second object (m2) divided by the square of the distance between them (r).

How is weight related to mass?

Mass is a measure of how much force it will take to change that path. Weight, on the other hand, is a measure of the amount of downwards force that gravity exerts on an object. This force increases with the object’s mass: the more inertia it has, the harder gravity pulls.

How much would a 70 kg man weigh on the moon what would be his mass on the moon and on the earth?

Now the mass of the man will be constant irrespective of whether he is on the Earth or on the moon since mass is an intrinsic property of matter. Hence the mass of man on Earth and the moon will be 70 kg.

How much force does a body with mass 20 KGS have?

A body with mass 20 kilograms and acceleration 5 m/s 2 will have a force Mass = 20 kgs Acceleration =5 m/s 2 = 20 x 5 = 100 Newtons

How do you find force if you know mass and acceleration?

Force = Mass/Acceleration = 70 kg x 9.8 m/s2 = 686 kg m/s2 = 686 N According to Newton’s second law of motion, force equals mass times acceleration. Therefore, if you know both mass and acceleration, you can find the force. In this case, the mass of the person and the acceleration due to gravity were known.

How do you calculate the force required to accelerate an 8kg object?

To illustrate, let’s first walk through an example in the metric system, where we’re calculating the force required to accelerate an 8 kg object at 10 m/s2. According to the “F = m a” formula, that force is: F = m a F = (8 kg) (10 m/s2) F = 80 kg m/s2

What is the force on a skydiver with a mass of 70 kg?

If a skydiver with a mass of 70 kg accelerates to Earth at a rate of 9.8 ms2 due to gravity What is the force on the skydiver Explain how you determined the answer and its units? Force = Mass/Acceleration = 70 kg x 9.8 m/s2 = 686 kg m/s2 = 686 N
