IT IS A DIRECTIONAL QUANITITY
IT CAN BE ZERO OR EQUAL TO SPEED BUT NEVER GREATER
EXAMPLE IF A BODY IS IN CIRCULAR PATH VELOCITY IS ZERO SINCE DISPLACEMENT IS 0 IF IT RETURNS TO ORIGNAL POSITION

Speed ascertains how fast a body moves.
velocity:Velocity ascertains the object's speed and the direction it takes while moving.

SPEED SHOULD BE POSITIVE
SPEED IS GREATER OR EQUAL TO VELOCITY
SPEED CAN NEVER BE ZERO
DETERMINES HOW FAST OR SLOW THE BODY IS MOVING
SPEED IS DISTANCE BY TIME
EXAMPLE IF BODY IS IN CIRCULAR PATH AND RETURNS TO THE ORIGNAL POSITION VELOCITY IS 0
AND SPEED IS CIRCUMFERENCE BY TIME TAKEN

Speed

It is the rate of change of distance.

It is a scalar quantity.

Speed can never be 0.

Speed=Distance/Time taken.

Ex: A race car in great speed in a race.

Velocity

It is the rate of change of displacement.

It is a vector quantity.

Velocity can be 0.

Velocity=Displacement/Time taken.

Ex: A car or a truck moving on a highway(straight road) at 25km/h.

# data[].attributes.body
THE AVERAGE SPEED WILL CONTINUE TO COUT EVEN IF THE DIRECTION CHANGES

# data[].attributes.body
- speed is a scalar quantity and velocity is a vector quantity.
- speed= distance/time
velocity= displacement/time
- speed can never be 0 but is positive
velocity can be zero, negative or positive
- speed ex: car moving along a path.50 km/h
velocity ex: bus moving along a straight path in a particular direction. 50 km/h North.

VELOCITY-Velocity can be defined as the rate at which an object changes position in a certain direction.

Vector quantity

Velocity can be zero, negative, or positive.

The velocity of the object changes with the change in direction, therefore the object must follow one direction.

An object may possess different velocities but the same speed.

example-ball dropped

SPEED-The rate at which an object covers a certain distance is known as speed.

Scalar quantity

Speed can never be negative or zero.

The average speed will continue to count even if the object changes direction.

Speed may or may not be equal to velocity.

example- car being driven 45 miles per hour

# data[].attributes.body
speed and velocity are equal because the body travels in 1 direction.then the body is said to have same constant velocity and speed

# data[].attributes.body
SPEED CAN NEVER BE NEGATIVE OR A ZERO

Speed: scalar quantity
Determines how fast a body is moving
Velocity : it is a vector quantity
Determines speed and direction of a body

SPEED
- it is how fast or how slow a object is moving
- it is a scalar quantity
-does not depend on direction
-constant Speed : if a body travels equal distance in equal interval of time .
- example : the car is moving at the speed of 60 km/hr

VELOCITY
-rate of displacement
-it is a vector quantity
-depends on direction
-constant velocity:if a body travels in a specified Direction in a straight line and moves equal distance in equal intervals of time
-example:the car is moving at the speed of 60 km\hr east

Speed-

speed is a scalar quantity

speed cannot be zero

distance is proportional to distance

speed=distance/time

ex: a race car moving fast

Velocity-

velocity is a vector quantity

velocity can be zero

displacement is proportional to velocity

velocity=displacement/time

ex: a bus moving on a bridge

constant speed and constant velocity are equal because in uniform velocity the body travels in specific direction and there is no change in direction so the BODY IS SAID TO HAVE EQUAL CONSTANT VELCOTIY AND SPEED

SPEED-

1) The rate at which an object covers a certain distance is known as speed.

2) It is a scalar quantity.

3) Speed does not depend on the direction of the object movement.

4) Uniform speed:- When an object covers equal distances in equal intervals of time, it is said to be moving with uniform speed.
Even if the object changes its directions, it is still said to be moving with constant speed.

5) EXAMPLE - A Car moving with a constant speed of 50km/hr, if changes its direction, it is still said to be moving with 50km/hr.

VELOCITY -
1) The rate at which an object changes its positions in a certain directions.

2) It is a vector quantity.

3) Velocity depends on the direction of the object's movement.

4) Uniform Velocity:- When an object covers equal distances in equal intervals of time, in a particular direction, it is said to be moving with uniform velocity.
If the body changes its direction, its velocity changes.

5) EXAMPLE - A car moving along a straight line, i.e., its moving in a particular direction, is said to have uniform velocity.
