Question

*)name the SI unit of the following
i)velocity
ii)distance
iii)speed
iv)time​

Answer 1

i) The SI unit of velocity is m/s.

ii) The SI unit of distance is the meter (m).

iii) The SI unit of speed is the meter per second (m/s), and the most common unit of speed is the kilometer per hour (km/h).

vi) The SI unit of time is second (s).

• Velocity is referred to the measurement of the rate and direction of change in the position of an object.
• It is specified both the speed of a body and its direction of motion.
• The distance is defined as the space between two objects.
• Speed is the rate at which an object covers distance.
• The time is a measurable period during the process.

Answer 2

1) Velocity: velocity is defined as the rate of change of displacement.

Velocity = distance/ time

So, the SI unit will be m/s

2)Distance: It is the actual path traversed by a particle.

SI unit of distance is m.

3)Speed: Speed is the rate of change of distance.

Speed = distance /time

so, the SI unit will be m/s

4)Time: The SI unit of time is seconds.
