yes, force (or weight) = mass * acceleration due to gravity
Yes
The weight of the object causes gravity to take the object falling
gravity can make an object weigh more or less depending on the gravity level. eg on earth you might weight 10 pounds and on mars you might weight 15 pounds but mas does not depend upon gravity.
You can't compare WEIGHT with MASS - those two are used to measure quite different things. It doesn't make sense to say that they are the same, or that they are different. You can only compare mass with mass, or weight with weight.
The force that makes objects have weight is called gravity. Gravity is the force of attraction between two objects with mass, such as the Earth and objects on its surface, that pulls them toward each other.
If the mass of the Earth became 3 times what it is today but the Earth remainedthe same size, then your weight would also become 3 times what you weigh today.
No it doesn't, earth's gravity is only making the moon orbiting the earth not give the moon gravity.
It's proportional to their weight ... which shows how hard the object is pulling the Earth towards itself. (As well as how hard the Earth is pulling - remember, it takes two objects to make a gravity field.)
To calculate a person's weight on Mercury, you would use the formula: Weight on Mercury = (Weight on Earth / 9.81 m/s^2) * 3.7 m/s^2. This is because Mercury's gravity is approximately 3.7 m/s^2, which is about 0.38 times the gravity on Earth.
Yes, if Earth gained mass, its gravity would increase, which would make your weight greater because you would experience a stronger gravitational force pulling you towards the center of the Earth.
Mass is a measure of how much matter is in an object, while weight is the force of gravity acting on that object. Gravity is the force of attraction between objects with mass, so mass and gravity are related in that gravity acts on objects with mass to create weight.
Tell them it is a pull that the earth and other things in space have that make things fall towards them.
