Question

define speed, Distance, Displacement, Acceleration, Retardation with mathematical expression. ​

Answer 1

$\huge \:answer$

1-->speed is defined as total distance travel by object in an unit time.. speed = distance / time. or s = d/ t. si unit = meter / seconds.

2--> the distance covered by and object is called distance

3--> the shortest possible length covered by a body between it's final and initial position

4--> In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities. The orientation of an object's acceleration is given by the orientation of the net force acting on that object.

SI unit: m/s2, m·s−2, m s−2

Dimension: L T −2

5--> an act or instance of retarding
