Question

9. Ratio of force and acceleration
measures:
a) Velocity
b) Force
c) Momentum
d) None of the above​

Answer 1

Answer:

Ratio of force and acceleration measures mass.

Force = Mass x Acceleration

Force / Acceleration = Mass

Hence answer is d) None of the above.

• Because Mass is not equal to velocity.
• It is not equal to force.
• It is not equal to momentum (mass x velocity)

Answer 2

Ratio of force and acceleration measures MASS (i.e. None of the above).

• We know that : Force is a vector quantity characterized by the product of mass and acceleration vector of the object.

Mathematically, we write :

$\therefore \: F = m \times a$

$\implies \: \dfrac{F}{a} = m$

$\implies \: \dfrac{Force}{acceleration} = mass$

So, force/acceleration measures mass.
