Question

Define the quantities - (a) Distance (b) displacement (C) velocity (d) acceleration and write
SI unit for each
​

Answer 1

Hey there!! :)

Here is your answer:

• Distance: The actual path followed by the body between two points is called distance.
• The SI unit of distance is m (metre).
• Distance is a scalar quantity.

• Displacement: The shortest path between two points in a specific direction is called displacement.
• The SI unit of displacement is same as distance i.e., metre (m).
• Displacement is a vector quantity.

• Velocity: The ratio of displacement of an object to the time taken is known as velocity of the object.
• The SI unit of velocity is m/s.
• It is a vector and derived quantity.

• Acceleration: The increase in speed with respect to time is called acceleration.
• It is also defined as the rate of change of velocity.
• The SI unit of acceleration is m/s^2.
• It is a vector and derived quantity.

Hope this helps!! ~~
