Forces Push & Pull

Forces Push & Pull

Pushes and pulls are the forces. They have their own directions.

Weight as Gravitational Force

Weight as Gravitational Force

Weight is the gravitational force acting on an object due to gravity.

Weight is the force and so it is measured in newtons (N).

Weight acts towards the centre of the Earth.

Mass and weight are not the same but the weight of an object depends on upon its mass. As mass increases, the weight of the object also increases.

Formula of Weight

Weight of an object given by the following formula

Weight = mass × gravity

W = m × g

W is the weight of the object measured in newtons (N)

m is the mass of the object measured in kilograms (kg)

g is acceleration due to gravity in m/s2

Gravitational Force on the Moon

The acceleration due to gravity "g" has a value of 1.6 m/s2 on the moon because the mass of the Moon is less than that of the Earth.

So the weight of an object on the Moon is less than the weight of the same object on the Earth.

The gravitational force on the surface of the moon is six times less than that of on the Earth.
