Slope of distance-time graph gives:

Correct option is D

(d) Speed

The slope of a distance-time graph represents speed because speed is defined as the rate of change of distance with respect to time. Mathematically, speed = distance/time.

Information Booster:

• Steeper the slope, higher the speed.
• A horizontal line means zero speed (object at rest).
• Curved graph indicates acceleration.
• Velocity-time graph slope gives acceleration.
• Area under velocity-time graph gives displacement.

Additional Information:

• Momentum = mass × velocity.
• Acceleration = change in velocity/time.
• Force = mass × acceleration (Newton’s Second Law).
