1. the dimension of force is MLT^-2
2.A vector has magnitude (how long it is) and direction: vector magnitude and direction. Unit Vector. A Unit Vector has a magnitude of 1:.
3. difference b/w speed and vector
- speed is has magnitude but vector have both magnitude and direction
- speed have only positive value but vector have both positive and negetive value .
s=ut + 1/2 at²
Consider an object which has travelled displacement s in the time t under uniform acceleration a.Let intial velocity of the object be u and the final velocity v.
s=1/2t(u+v) -1
from the veocity relation
v=u+at -2
substitute 1 in 2
s=1/2t(u+u+at)
=1/2t(2u+at)
s=ut+1/2at^2
Hope it helps and pls mark it as the best.
