- The acceleration due to gravity (g) is 9.8 m/s², applicable when an object is in free fall near Earth’s surface with negligible air resistance.
- Velocity under constant acceleration is calculated using v = v₀ + gt, where v₀ is initial velocity, g is gravitational acceleration, and t is time.
- Distance fallen from rest is calculated using y = ½gt², derived from the average velocity over time multiplied by time.
- In the graph, segment A represents constant velocity (zero acceleration), B shows increasing velocity (positive acceleration), C indicates constant velocity again, and D shows decreasing velocity (negative acceleration or deceleration).
- For free fall starting from rest (v₀ = 0), after 1 second, velocity is 9.8 m/s, and distance fallen is 4.9 meters.
