The difference between speed and velocity is that velocity includes

speed is a scalar quantity i.e they only possess magnitude but no direction compared to velocity being a vector quantity has both magnitude and direction.

Explanation:

It is evident that speed are used interchangeably with velocity and this is majorly due to the similarities in their units but they have their differences as well in that speed is a scalar quantity i.e they only possess magnitude but no direction compared to velocity being a vector quantity which has both magnitude and direction.

Also, speed has to do with rate of change of distance and velocity is rate of change of displacement.

Speed is scalar and Velocity is Vector

Explanation:

the word that best describes martin luther king jr.'s tone in the video is dignified

martin luther king, jr. was a social activist and baptist minister who played a key role in the american civil rights movement from the mid-1950s until his assassination in 1968. the video shows his manner and attitude having or showing a composed or serious manner that is worthy of respect so dignified is the correct answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
