Question

1) define displacement . is displacement a scalar quantity? 2) is the displacement of a body is zero,is the distance covered by it necessarily be zero? 3) under what condition will the distance & displacement of a moving object have same magnitude

Answer 1

displacement is the shortest distance covered by an object

Answer 2

• ☛Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
• ☛Displacement is the measurement of the length of the shortest path from the initial point to the final point. ... Distance is a scalar quantity whereas displacement is a vector quantity. Distance is the total path covered by the body and displacement is the shortest path covered by the body.
• ☛ Velocity is the rate of change of displacement.
