Which statement best explains the difference between velocity and speed? a) speed is a vector and requires a direction to completely describe it. b) velocity is a vector and requires a direction to completely describe it. c) speed is measured in units of meter and velocity is measured in units of meters per second. d) velocity is measured in units meters per second and speed is measured in units of miles per hour.

Answer by mimiwhatsup: B) Velocity is a vector and requires a direction to completely describe it.

Velocity is the speed and direction of an object in motion.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
