Question

6. Differentiate between the following:
a. Acceleration due to gravity and gravitational force
b. Buoyancy and upthrust​

Answer 1

Answer:

Explanation:

a.Every object in the universe exert gravitational pull to other objects. When the gravitational pull is exerted by Earth it is call Gravity. So gravity is the pull by earth. Whereas acceleration due to gravity is acceleration by which any object cmes towards the earth within its gravitational field.

b.As discussed, the buoyant force is the upward force exerted on an object that is wholly or partly immersed in a fluid. This upward force is also called as Upthrust. It is due to the buoyant force that a body submerged partially or wholly in a fluid appears to lose its weight i.e. appears to be lighter.

Answer 2

Explanation:

a. Every object in the Universe exert gravitational pull to other objects. When gravitational pull is exerted by Earth it is called Gravity. So gravity is the pull by earth. Whereas acceleration due to gravity is acceleration by which any object towards the earth within its gravitational field.
