RRB Technician Grade III Official Paper (Held On: 28 Dec, 2024 Shift 2)

Answer 1

The correct answer is 0m, 10m.

Key Points

Displacement is the shortest distance between the initial and final position of the body.
Total displacement is 0m because the body returns to its starting point.
Distance is the total path covered by the body.
Total distance covered is 10m, as it travels 5m up and 5m down.

Additional Information

Displacement vs Distance
- Displacement is a vector quantity with both magnitude and direction.
- Distance is a scalar quantity and only considers the magnitude.
Free Fall
- It is the motion of a body where gravity is the only force acting upon it.
- In free fall, the body gains speed as it descends.
Projectile Motion
- It involves objects thrown into the air, affected by gravity and air resistance.
- The motion can be analyzed in two dimensions: horizontal and vertical.
Acceleration Due to Gravity
- The acceleration experienced by an object due to Earth's gravitational pull is approximately 9.8 m/s².
- This value remains constant near the surface of the Earth.
