Use an example to describe the difference between tangential and centripetal acceleration

Say you are holding a thread to the end of which is tied a stone. Now when you start whirling it around you will notice that two forces have to be applied simultaneously. One which pulls the thread inwards and the other which throws it sideways or tangentially.

Both these forces will generate their respective accelerations.

The one pointed inwards will generate centripetal or radial acceleration.

The one pointing sideways will generate tangential acceleratio

Explanation:

A major difference between tangential acceleration and centripetal acceleration is their direction

Centripetal means “center seeking”. Centripetal acceleration is always directed inward.

Tangential acceleration is always directed tangent to the circle.

Tangential acceleration results from the change in magnitude of the tangential velocity of an

object. An object can move in a circle and not have any tangential acceleration. No tangential

acceleration simply means the angular acceleration of the object is zero and the object is moving

with a constant angular velocity

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
