Geoghegan's letter in your issue of April 7 (vol. xxxv. p. 534), my experience in teaching physics long ago led me to the same conclusions. For three years I have used in my classes in this the oldest existing University in Ontario, and with the greatest advantage, the terms...
What Is Weight in Physics? Weightis the result of gravity acting on mass: w = mg. The value of g on Earth's surface is 9.8 m/s3with units ofacceleration. To find the weight of something, simply multiply its mass by the value of the local gravitational field, and you get a result ...
The goal of this study was to elicit and juxtapose the account of the concept of weight in history vis a vis physics education. The results reveal the prob

Enter two units to convert From: To: Definition: MillinewtonThe SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.So 1 millinewton = 10-3 newtons.The definition of a newton is as follows:In physics, the newton (symbol: N) is the SI unit of force,...
Very often, the units can be used interchangeably in questions. Let us see how both the units are the same. 10 Nkg−110 ms−210 Nkg−110 ms−2 We know, F =m × aF =m × a Let us put the units of the different elements. N = kg× ms−2N = kg× ms−2 Let us...

In physics, each object has a unit that determines the standard measurement of that body. Therefore, a physical quantity such as mass also has a unit. In International systems, SI, the mass is measured in Kilograms denoted by the symbol kg. ...
The SI unit of force (and hence weight in the mechanics sense) is the newton (N) – which can also be expressed in SI base units as kg·m/s² (kilograms times meters per second squared).The gravitational force exerted on an object is proportional to the mass of the object, so it...
same as mass; while mass is the amount of matter in an object and remains constant regardless of location, weight can change depending on the gravitational pull of the planet or moon an object is on. The standard unit of weight in the International System of Units (SI) is the newton (N...
