Question

17. If we denote speed by S, distance by D
and time by T. the relationship between
these quantities is S = 1/Tx D.
O True
O False​

Answer 1

Speed - S

Distance - D

Time - T

Speed of the object is the distance covered by the body per unit time. The relationship between these quantities is $S = \dfrac{D}{T}$. Therefore, false is the correct option.

Answer 2

True

Know why:

Speed — Distance travelled by a particle in unit time.

clearly,

if speed = S, D = distance and T = time,

∴ S = D/T

⇒ S = 1/T × D (proved).

In circular motion,

• ω = θ/∆t
• a = ∆ω/∆t
• v (linear velocity) = rω

where,

1. ω (omega) = angular velocity,
2. θ = angular displacement,
3. t = time taken,
4. r = radius.
