please answer this questions I will mark them brillant
Answers
Answer:
the force exerted by earth in which if you throw an object towards the earth gets pulled by the earth . The S.I unit of force is newton
Answer:
1)The force of attraction between particles of matter , whether terrestrial or celestial is known as gravitational force.
The SI unit of force is N i.e. Newtons.
2)Mass is the amount of matter present in an object.
Weight is the force by which earth pulls an object towards itself. Also-
Mass is measured by a beam balance and
weight is measured by a spring balance. Also-
SI unit of mass is kg and SI unit of weight is N (newtons).
3)Static friction is the friction that forces to keep an object at the position of rest.
It is applied on stationary objects and has the greatest values , when compared with other types of friction
