Question

Define:-
i) Velocity
ii) Heat
​

Answer 1

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time.

Heat is the form of energy that is transferred between systems or objects with different temperatures

Answer 2

Answer:

The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). Velocity is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of bodies.

Hey dear I just know velocity's answer so here it is
