- mass and weight
- what is mass
- mass is defined as the amount of matter in a body
- it is measued in kilograms(kg)
- its a scaler quantity

- it is measued in kilograms(kg)

- mass is defined as the amount of matter in a body
- what is weight
- weight is a force and is a meaure of the size of gravitionalal pull on a ob ject exerted
- near the surface of the earth,there is a force of 10N on each 1 kg of mass
- we say that the earths gravitational field strengh, g, is 10 N/kg

- near the surface of the earth,there is a force of 10N on each 1 kg of mass
- the equation for weight
- weight(N) = mass (kg) x acceleration due to gravity (m/s sqaured)

- measured in newtons.vector quantity so it has size and direction
- why is weight a force
- due t the pull of gravity on the object

- weight is a force and is a meaure of the size of gravitionalal pull on a ob ject exerted
- the value of g is rougly the same everywhere on earths surface
- but the further you move away from earth,the smaller g becomes
- in sace far away from plants,he gravitational force is 0 and its said to be weightless

- but the further you move away from earth,the smaller g becomes
- on earth,the pull of gravity is 10N on a mass of 1 kg
- the value of g is rougly the same everywhere on earths surface
- but the further you move away from earth,the smaller g becomes
- in sace far away from plants,he gravitational force is 0 and its said to be weightless

- but the further you move away from earth,the smaller g becomes
- gravitation feild strengh (g)= 10N/kg

- the value of g is rougly the same everywhere on earths surface
- divid the g by 1000 o get the mg
- the size of g also gives the gravitational acceleration,because from newtons second law
- acceleration = f divided by m
- g= w divided by m
- the alternative set of units for g is m/s sqaured

- g= w divided by m

- acceleration = f divided by m

- what is mass
