Mass and Weight
What is mass?
The mass of an object is the amount of matter in the object and is measured in Kg
1Kg = 1 000 000g
1Kg = 1000g
1Kg = 1ton
What is weight?
Weight is the force exerted on an object by gravitational force.
Weight (Fg) is a force and is measured in newton (N)
When does the weight of an object change?
The weight of an object will change if the gravitational force on the object changes.
The weight of an object will be one sixth of its weight on earth.
What is the formula for weight?
Weight = mass × gravitational.
acceleration
Fg = mg
Gravitational acceleration for:
> Earth g = 9,8 m/s
> Moon g = 1,6 m/s
On Earth an object with the mass of 1Kg has a weight of 9,8N.
What is gravitational acceleration?
Gravitational acceleration (g) is the acceleration as a result of gravitational force and amounts to how fast objects are being attracted to the Earth or centres of other places.
What is a Newton meter ( newton spring balance)?
It is callibrated in newton and used to measure the magnitude of the mass of an object.
