A car is moving along a straight line. It's displacemetn (x)- time (t) grapg is shown in column II. Match the entries in column I with points on graph.
Text Solution
Verified by Experts
The correct Answer is:
1(A) = S, (B) = Q, (C ) = R
In `x - t` graph slope decides the velocity & curvature decides the acceleration i.e. `{:("slope positive",rArr,"v positive",),("slope negative",rArr,"v negative",),("concave upward curvature",rArr,"a positive",),("concave downward curvature",rArr,"a negative",):}`
