(i) Uniform Acceleration:
Uniform acceleration refers to the motion of an object where its velocity changes at a constant rate over equal intervals of time. In simpler terms, it means that the object’s speed increases or decreases by the same amount in each equal interval of time. Mathematically, this translates to a consistent change in velocity per unit of time.

Displacement refers to the straight-line distance and direction between an object’s initial and final positions. While an object may cover a certain distance during motion, its displacement can be zero under specific conditions based on the path taken.
Explanation with Example:
1. Scenario:
– Consider an object initially positioned at point A.
– The object moves along a path that forms a closed loop or returns to its starting point.
2. Motion and Distance Covered:
– The object moves through a certain distance during its motion, traversing a path around the loop or circuit.
3. Displacement Calculation:
– Despite the object covering a distance, its displacement is determined by the shortest straight-line distance between the initial and final positions.
– In the case of the object returning to its starting point, the final position coincides with the initial position (A).
4. Zero Displacement Example:
– For instance, if the object moves in a closed loop, following a circular path, and eventually ends up back at point A.
– Although the object has covered a distance around the loop, the displacement between the initial and final positions (A to A) is zero.
– This is because displacement considers the shortest straight-line path between positions, which, in this case, is non-existent as the object returns to its starting point.
Conclusion:
The scenario exemplifies that while an object may traverse a distance during its motion, it can have zero displacement if it returns to its initial position or follows a closed loop. Displacement considers the shortest straight-line distance between positions, and in cases where an object ends up at the starting point, its displacement is zero despite covering a certain distance.

Explanation of Displacement:
1. Magnitude and Direction:
– Displacement has both magnitude and direction, making it a vector quantity. It considers the shortest straight-line path between the initial and final positions of an object.
2. Possible Scenarios:
– Displacement can be positive, negative, or zero, depending on the direction of motion concerning the reference point. It considers the change in position, not the total distance covered by the object.
3. Relation to Distance Travelled:
– Displacement can be equal to, less than, or greater than the distance travelled by the object.
– If an object moves in a straight line without changing direction, displacement’s magnitude equals the distance travelled.

Displacement is a vector quantity in physics that refers to the straight-line distance and direction between an object’s initial position and its final position. It is a fundamental concept used to describe the change in position of an object during its motion.
Explanation of Displacement:
1. Magnitude and Direction:
– Displacement has both magnitude and direction, making it a vector quantity. It considers the shortest straight-line path between the initial and final positions of an object.
2. Possible Scenarios:
– Displacement can be positive, negative, or zero, depending on the direction of motion concerning the reference point. It considers the change in position, not the total distance covered by the object.
3. Relation to Distance Travelled:
– Displacement can be equal to, less than, or greater than the distance travelled by the object.
– If an object moves in a straight line without changing direction, displacement’s magnitude equals the distance travelled.
– However, if the object changes direction or returns to its starting point, displacement’s magnitude can be less than the total distance covered.
Properties of Displacement:
1. Vector Quantity: Displacement has both magnitude and direction, requiring both numerical value and specified direction for complete description.
2. Shortest Path Consideration: It measures the shortest straight-line distance between the initial and final positions, irrespective of the actual path taken by the object.
3. Relation to Motion: Displacement provides crucial information about an object’s change in position, aiding in understanding motion characteristics like speed, velocity, and acceleration.
Conclusion:
See lessDisplacement, as a vector quantity, signifies the change in position of an object from its initial to final locations. It incorporates both magnitude and direction and differs from the total distance travelled, considering the shortest straight-line path between positions. Understanding displacement is essential in analyzing and describing an object’s motion accurately.
