Newton`s First Law of Motion
... Weight–a measure of the gravitational force acting on an object – Weight depends on an object’s location – The weight of an object would be very different on the earth and on the moon, and still different in outer space – On the moon, the object would have only one-sixth the weight it has on the ear ...

... A ball has a mass of 10 kg on Earth. Will its mass be more or less on the moon? Neither, the mass will be the same in both locations because the mass of an object does not change. What about the weight? The ball will weigh more on the Earth than the moon because there is more gravity on Earth. ...

... A simple example is in the case of biceps muscle and radius bone acting to support a weight W in the hand (Fig 2a),(Fig 2b) shows the forces and dimensions of a typical arm. There are only two torques: that due to the weight W, which is equal to 30W acting clockwise and that produced by the muscle ...

Forces and Motion
... Our atmosphere is a giant mixture of gases (a fluid), so it exerts pressure on everything in and around it. An air molecule at a low elevation has a lot of air molecules above it, and their weight is pressing down on it. This means that it is being squeezed into a smaller space and pushed closer to ...
