Assertion : In the s-t graph as shown in figure, velocity of particle is negative and acceleration is positive.

Reason : Slope of s-t graph is negative and increasing in magnitude.

Assertion : In displacement-time graph of a particle as shown in figure, velocity of particle changes its direction at point A. Reason : Sign of slope of s-t graph decides the direction of velocity.

Assertion : In displacement-time graph of a particle as shown in figure, velocity of particle changes its direction at point A. Reason : Sign of slope of s-t graph decides the direction of velocity.

The position time graph of a particle is shown below. The point where velocity is negative and acceleration is positive is х a b

s-t graph shown in figure is a parabola. From this graph we find that :

For the acceleration - time (a - t) graph shown in figure, the change in velocity of particle from t = 0 to t = 6 s is

For the acceleration - time (a - t) graph shown in figure, the change in velocity of particle from t = 0 to t = 6 s is

A : The displacement (s) time graph shown in the figure represents an accelerated motion. R : Slope of graph increases with time.

A : The displacement (s) time graph shown in the figure represents an accelerated motion. R : Slope of graph increases with time.

Can position-time graph have negative slope ?

Draw the x to t graphs for positive, negative and zero acceleration.
