Mass is a measure of the amount of matter (stuff) in an object. It is measured in kilograms (kg) Weight is a force and it is the pull of gravity acting on an object. It is measured in Newtons. Collect a 20N spring balance and a set of 100 g masses. Predict the weight (force of gravity) on 100 g. Record this in the table.
3.1 Introduction. Unusually in physics, there is no pithy phrase that sums up the study of dynamics (the way in which forces produce motion), kinematics (the motion of matter), mechanics (the study of the forces and the motion they produce), and statics (the way forces combine to produce equilibrium).
m = Mass. Velocity of body travelling in circle. Centripetal acceleration. Centripetal force. Force experienced by 2 masses (Newton’s law of gravitation). Field strength as experienced by a mass in the field. Field strength at a certain distance from body. F = Force. G = Gravitational constant. M = Mass of body. m = Mass of body (in a field).

In general, when converting from base units (m, l, g, etc) or derived units (m2,m3, m/s, Hz, N, J, V, etc) to a multiple greater (kilo, mega, giga, or tera) than the base or derived unit- then divide by the factor. For example: 10m = 10/1000km = 1/100 km = .01km. When converting from base units or derived units to a multiple smaller (centi ...

Weight is a force, so it is a vector quantity. The SI units for force are newtons (N) Weight is the effect of a gravitational field on a mass. Weight is defined as: The force acting on an object due to gravitational attraction. Planets have strong gravitational fields.
