Distance-Time Graph | |
Horizontal Axis | Time (t) |
Vertical Axis | Distance (s) |
Gradient Formula | Gradient = Δs / Δt (Speed) |
Example 2.5 | |
From Peshawar to Rest Area | 100 km / 1 hr = 100 km/hr = 27.78 m/s |
From Rest Area to Islamabad | 75 km / 1.5 hr = 50 km/hr = 13.89 m/s |
Total Distance | 175 km / 2.5 hr = 70 km/hr = 19.44 m/s |
Speed-Time Graph | |
Horizontal Axis | Time (t) |
Vertical Axis | Speed (v) |
Slope Formula | Slope = Δv / Δt (Acceleration) |
Area Under Graph | Distance Traveled |
Example 2.6 | |
Acceleration (0-20 s) | 1.5 m/s² |
Acceleration (20-50 s) | 0 m/s² |
Acceleration (50-60 s) | -3 m/s² |
Total Distance | 1350 m |
Average Speed | 22.5 m/s |
