Question

Which of the Quantities, speed, or Velocity gives the direction of motion of the body?
A. Speed.
B. Acceleration.
C. Velocity.
D. All of the above.

Answer 1

Hint:Speed is the scalar quantity and velocity is the vector quantity here velocity gives the direction of the motion of the body
The speed doesn’t have direction and velocity has its direction. The speed and velocity of the body are equal when the body is moving in a straight line.
The physical quantity which has both speed and direction of the motion of the body is said to be a velocity.

Complete step-by-step solution:
The velocity of an object is the rate of change of position concerning time. The velocity is equal to the specification of an object’s speed and direction of motion. This is the fundamental concept of kinetics. if there is a change in speed, direction, or both then the particular object has a change in velocity. and it is said to be undergoing acceleration.
The average velocity is always less than or equal to the average speed of the object.
An example of velocity is considering the person moving rapidly like one step forward and backward always returning to the original starting position; here it gives the zero velocity.
 it designates how fast in what direction a point is moving. This point always moves in the direction tangent to its path.
if the object moves on the right side then the velocity is described as rightwards. if the object moves downward then the velocity is described as downwards.
Hence the answer is option(C) velocity.

Note:Generally, the Velocity is a vector quantity that depends on the speed of the body and direction to travel. Velocity is less than or equal to the average speed of the object.
To have a constant velocity the object should have a constant speed in a constant direction.
