How can I calculate weight?

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 the weight speed?

While the mass is normally considered to be an unchanging property of an object, at speeds approaching the speed of light one must consider the increase in the relativistic mass. 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.

What is correct weight and height for age?

Weight and height guide chart

Height Weight
5ft (60″) 97 to 123 lbs . 128 to 148 lbs.
5ft 1″ (61″) 100 to 127 lbs. 132 to 153 lbs.
5ft 2″ (62″) 104 to 131 lbs. 136 to 158 lbs.
5ft 3″ (63″) 107 to 135 lbs. 141 to 163 lbs.

What is the force of weight?

Weight is the result of gravity . The gravitational field strength of Earth is 10 N/kg (ten newtons per kilogram). This means an object with a mass of 1 kg would be attracted towards the centre of Earth by a force of 10 N. We feel forces like this as weight.

What is correct weight and height for age in KG?

What is difference between speed and velocity?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. … For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.

What is the relationship between weight and speed?

Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

According to Sir Isaac Newton, the force of an entity equals its mass, multiplied by acceleration. This basic principle is what is used to calculate load force, which is the force that opposes that entity. … Apply Sir Isaac Newton’s formula: force = mass x acceleration.

What is value of g?

Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location.

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.

How do you calculate weight and height?

Body Mass Index is a simple calculation using a person’s height and weight. The formula is BMI = kg/m2 where kg is a person’s weight in kilograms and m2 is their height in metres squared. A BMI of 25.0 or more is overweight, while the healthy range is 18.5 to 24.9.

What are 5 differences between speed and velocity?

Speed is the rate of change of distance whereas velocity is the rate of change of displacement.

Speed & Velocity.

Speed Velocity
Speed is a scalar quantity Velocity is a vector quantity.
Speed ascertains how fast a body moves. Velocity ascertains the object’s speed and the direction it takes while moving.

Can velocity be negative?

An object which moves in the negative direction has a negative velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a positive acceleration).

How do we calculate velocity?

Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.

Does weight affect top speed?

Adding extra weight to your car will slow acceleration, but won’t reduce its top speed. … In determining a car’s top speed, its engine battles two main forces: rolling resistance and aerodynamic drag.

Does height affect velocity?

Yes, height does increase the final velocity of a falling object.

Does weight affect speed of falling?

Heavier things have a greater gravitational force AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.

How do I know if I am overweight for my age?

Based upon your BMI, you can find out if you are:

• Underweight: It means your BMI is less than 18.5.
• In normal or healthy weight range: If your BMI is 18.5 to 24.9.
• Overweight: If your BMI is 25.0 to 29.9.
• Obese: If your BMI is 30.0 or more.
