Question

1-Assertion : For a particle, acceleration-time graph gives the velocity.
Reason : Rate of change of velocity is acceleration.

(a) Both, A and R, are true and R is the correct explanation of A.

(b) Both, A and R, are true but R is not the correct explanation of A.

(c) If A is true but R is false.

(d) If A is false but R is true.

2-Assertion: A body having non zero acceleration can have a constant velocity. Reason: Acceleration is the rate of change of velocity.

(a) Both, A and R, are true and R is the correct explanation of A.

(b) Both, A and R, are true but R is not the correct explanation of A.

(c) If A is true but R is false.

(d) If A is false but R is true.

3-Assertion: Area under velocity-time graph give displacement. Reason: Area under acceleration-time graph give velocity.

(a) Both, A and R, are true and R is the correct explanation of A.

(b) Both, A and R, are true but R is not the correct explanation of A.

(c) If A is true but R is false.

(d) If A is false but R is true

4-Assertion : Position-time graph of a stationary object is a straight line parallel to time axis.
Reason : For a stationary object, position does not change with time.

(a) Both, A and R, are true and R is the correct explanation of A.

(b) Both, A and R, are true but R is not the correct explanation of A.

(c) If A is true but R is false.

(d) If A is false but R is true

5- Assertion : The position-time graph of a body moving uniformly is a straight line parallel to position-axis.
Reason : The slope of position-time graph in a uniform motion gives the velocity of an object.

(a) Both, A and R, are true and R is the correct explanation of A.

(b) Both, A and R, are true but R is not the correct explanation of A.

(c) If A is true but R is false.

(d) If A is false but R is true​
