Question

define initial position and final position

Answer 1

(20%) What is the initial position, velocity and acceleration both at t = 3 seconds, of an object for the given equation of x(t) = 4 t2 – t/2 – 8.






A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P. It quantifies both the distance and direction of an imaginary motion along a straight line from the initial position to the final position of the point.

Answer 2

define initial position and final position

ANSWER:-

• In physics, the initial position of an object is the position from which its motion starts or begins.

• In physics, the Final position is the position in which it comes to the rest.

• Displacement is a vector quantity and hence has both magnitude and direction. The magnitude of displacement is proportional to the linear distance between initial and final positions along the straight line enlisting two positions which means it is the shortest distance between initial and final positions.

• We always work out for displacement by subtracting the initial position from the final position.

• The magnitude of the displacement is invariably positive which means it is the absolute value of the displacement because displacement is a vector and cannot have a negative value of magnitude as the final position is always greater than the initial position.
