The shortest distance measured from the initial to the final position of an object is known as ________.
acceleration
velocity
displacement
speed
displacement
The shortest straight-line distance measured from the initial position to the final position of an object is defined as displacement. It is a vector quantity, meaning it has both magnitude and direction.
The shortest straight-line distance measured from the initial position to the final position of an object is defined as displacement. It is a vector quantity, meaning it has both magnitude and direction.
If you walk in a large circle to return to your starting point, your total distance travelled might be 400 meters, but your displacement is 0 because your initial and final positions are identical.
Remember 'Displacement is Direct' тАФ it is the direct line from start to finish.
╬Фx=xfтАЛтИТxiтАЛ тАФ where ╬Фx is displacement, xfтАЛ is final position, and xiтАЛ is initial position.
In physics, motion is described by how an object changes its position over time. While the total length of the path covered is called distance (a scalar quantity), displacement represents the change in position vector, expressed as d=xfтАЛтИТxiтАЛ, where xfтАЛ is the final position and xiтАЛ is the initial position. Because it is the shortest path, its magnitude is always less than or equal to the total distance travelled.
Displacement is a vector quantity (has magnitude and direction).
SI unit of displacement is the meter (m).
Displacement can be positive, negative, or zero.
Distance is always non-negative and is a scalar quantity.
Useful for calculating average velocity.
Essential in vector mechanics for determining net change in position.
Does not provide information about the actual path taken by the object.
Navigation and GPS systems.
Calculating the net change in state for physical systems.
Acceleration is the rate of change of velocity, not distance.
Velocity is the rate of change of displacement with respect to time.
Speed is the scalar rate of change of distance with respect to time.
C is correct тАФ Displacement is defined as the shortest straight-line path between two points in space.
In competitive exams, always check if a question asks for a 'scalar' (distance/speed) or a 'vector' (displacement/velocity). If the path involves a turn, distance will always be greater than the magnitude of displacement.
