Assertion : The slope of displacement-time graph of a body moving with high velocity is steeper than the slope of displacement-time graph of a body with low velocity.
Reason : Slope of displacement-time graph = Velocity of the body.

Assertion : A body, whatever its motion is always at rest in a frame of reference which is fixed to the body itself.
Reason : The relative velocity of a body with respect to itself is zero.
| Assertion (A): | Displacement of a body may be zero when distance travelled by it is not zero. |
| Reason (R): | The displacement is the longest distance between initial and final position. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |

Assertion : The equation of motion can be applied only if acceleration is along the direction of velocity and is constant.
Reason : If the acceleration of a body is constant then its motion is known as uniform motion.

Assertion : The relative velocity between any two bodies moving in opposite direction is equal to sum of magnitude of the velocities of two bodies.
Reason : Sometimes relative velocity between two bodies is equal to difference in magnitude of velocities of the two.

Assertion : The displacement-time graph of a body moving with uniform acceleration is a straight line.
Reason : The displacement is proportional to time for uniformly accelerated motion.
| Assertion (A): | Velocity-time graph for an object in uniform motion along a straight path is a straight line parallel to the time axis. |
| Reason (R): | In uniform motion of an object velocity increases as the square of time elapsed. |
