Question

2. Identify the base quantity in the following:
(i) Speed (ii) Area (iii) Force (iv) Distance​

Answer 1

Answer:

Answer is as follows

Explanation:

1. Speed :

• The rate of change in the position of an object in any direction is known as speed.
• Speed is a scalar quantity.
• Speed has only direction and no magnitude.
• The formula for speed is $s = \frac{d}{t}$.
• The unit of speed is $ms^{-1}$.

2. Area :

• The total space taken by a 2D surface or any object is the area of that object.
• The unit of area is $m^{2}$ or $cm^{2}$.
• Different objects have different formulas for calculating area.
• E.g. Area of square is $(side)^{2}$.

3. Force :

• The push or pull applied on an object that causes the change in the velocity of the object is known as force.
• Force the vector quantity.
• Force has both direction and magnitude.
• Formula for force is f = ma (Force = Mass * Acceleration).
• Unit of Force is Newton.

4. Distance :

• The total movement of an object without considering the direction used by the object is the Distance travelled by that object.
• Distance is a scalar quantity.
• Distance has only magnitude and no direction.
• Unit of distance is m or cm or km etc.
