Tossing a ball up repeatedly will do the trick. It will fall. You can catch it when it comes down and toss it back up. It won't not come back down. Gravity has a firm hold on it, and it won't let go.
Gravity is dependent on mass and distance between objects. The formula for calculating the force of gravity between two objects is F = (G * m1 * m2) / r^2, where G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between their centers. The greater the mass and the smaller the distance between objects, the stronger the gravitational force.
Gravity has never been detected. It remains one of the mysteries of physics because no wave or particle has ever been detected, but all indications are that it must exist. One of the reasons that is is not detectable is because it is like a quiet pond where all the water is still, because everything is in such close balance in the Universe. If you drop a pebble in the pond, you will see the pebble and the ripples. Scientists have not yet been able to see a 'pebble' or 'ripple' in the pond that is called the force of gravity; one of the four basic forces in the universe along with the weak force, the strong force, and the electromagnetic force. ya know what, i think you can detect it. hold up an apple and let go. if it falls, there is gravity
Gravity is always measured in interaction between two masses, for it must act between two masses (it pulls two objects together). If you only have one object, there is no gravitational force. You will see why if you put a 0 as one of the two masses in the formula.
The formula for calculating gravitational force is:
F = G(m1m2) / r2
- G is the gravitational constant, a very small number representing the strength of gravity; as far as we know, this should always be 6.67 * 10-11 in anything you are calculating.
- r is the distance between the centres of the masses.
- m1 is the mass (in kilograms) of the first object, and m2 is the mass of the second.
This will give you F, the force of gravity in Newtons.
Here's what you would do with calculating the gravity between a 100kg object on Earth and the Earth itself:
G = 6.67 * 10-11
m1 (this will be the 100kg person) = 100kg
m2 (earth, of course) = 5.97219 * 1024
r (pretty much the radius of Earth; we can consider this object on the surface) = 6,378,137 meters
Now:
F = 6.67*10-11(100 * 5.97219*1024) / 63711372
Throw that into a calculator and get:
9.81353687175 N
Drop a wright from a height s and measure the time to fall t, s= 1/2 gt2.
Gravity is then measured by g= 2s/t2.
The equation to calculate an object's weight is weight = mass x gravity, where mass is the amount of matter in an object and gravity is the acceleration due to gravity at that location (usually 9.8 m/s^2 on Earth).
The term for the amount that something weighs is "weight." Weight is a measure of the force of gravity acting on an object.
The force of gravity on an object is determined by its mass and the acceleration due to gravity. The formula to calculate this force is: force of gravity = mass of the object × acceleration due to gravity. On Earth, the acceleration due to gravity is approximately 9.81 m/s^2.
Weight is the force exerted on an object by gravity, measured in newtons (N). The force of gravity acting on an object determines its weight. The formula to calculate weight is weight = mass x gravity, where mass is the amount of matter in an object and gravity is the acceleration due to gravity.
Weight is the amount of force with which gravity is pulling down on something, measured in newtons (N) or pounds (lbs). It is calculated by multiplying an object's mass by the acceleration due to gravity (9.8 m/s^2 on Earth).
weight
it is measuring
You would use a device called a dynamometer to measure the amount of force required to pull something. Dynamometers typically come in forms such as a spring scale or electronic load cell. They are commonly used in various industries for testing and measuring purposes.
It is a determined value or an estimate.
Calculate means to determine (the amount or number of something) mathematically.
The acceleration of gravity can be calculated using the formula a = 9.81 m/s^2, where "a" represents the acceleration due to gravity. This value is a constant for objects falling in Earth's gravitational field.
Your mass is the amount of stuff that makes up our body. It can only change if you either remove something from your body or add something to it. Your weight is the amount of force you experience from gravity. It depends on both your mass and the strength of the gravity. Since the strength of gravity varies between the planets, so will your weight.
Weight and mass is not the same.Mass is the amount of matter something has while weight is the amount of gravity exerted on something. The mass of an object never changes no matter where you go, but weight does. For example, if an object weighs 10 kg on Earth, it would weight a lot more on the Jupiter because of the Jupiter's greater gravity. However, the mass would stay the same. Weight is related to mass.Weight = mass x amount of gravity.
Weight is the force exerted on an object due to gravity. It is the mass of the object multiplied by the acceleration due to gravity. The greater the mass of an object, the greater its weight will be when subjected to the same gravitational force.
Mass is a measure of the amount of matter in an object, weight is the force of gravity on an object. Weight is directly proportional to mass and gravity: (Weight = mass \times gravity). On Earth, gravity is relatively constant, so an object's weight is a good indicator of its mass.
by bottle method
No. Mass is the amount of material in your body. Your weight is determined by gravity, and will increase as gravity increases, but the actual mass of your body is not affected by gravity.
