# NEET Physics Kinematics (Graphical Questions)

Question 1:

Solution:

Question 2:

Solution:

(a) The slope of displacement-time graph goes on decreasing, it means the velocity is decreasing i.e. It’s motion is retarded and finally slope becomes zero i.e. particle stops.

Question 3:

Solution:

(d) In the positive region the velocity decreases linearly (during rise) and in the negative region velocity increases linearly (during fall) and the direction is opposite to each other during rise and fall, hence fall is shown in the negative region.

Question 4:

Solution:

(b) Region OA shows that graph bending toward time axis e. acceleration is negative.

Region AB shows that graph is parallel to time axis i.e. velocity is zero. Hence acceleration is zero.

Region BC shows that graph is bending towards displacement axis i.e. acceleration is positive.

Region CD shows that graph having constant slope i.e. velocity is constant. Hence acceleration is zero.

Question 5:

Solution:

Question 6:

Solution:

(c) In part cd displacement-time graph shows constant slope e. velocity is constant. It means no acceleration or no force is acting on the body.
