Question

So how do rotational values connect to translational values here? How do the equations look like here? Where might you use this in your everyday life?

Answer 1

In translational motion, equations are

In rotational case, we have

i.e., linear displacement (s) is replaced by angular displacement ,

linear velocity (v) is replaced by angular velocity , and

linear acceleration (a) is replaced by angular acceleration

We can use them in calculting the time we would require to reach some place, if we know our speed, car's acceleration.

We can use them in calculating fann's number of revolutions per second.

We can use them in noting time a body will take to fall down from a certain place.
