Detailed explanation-1: -the impulse and momentum has same unit of measurement. In SI unit, kg⋅m/s = N⋅s. Momentum is the quantity of motion of a moving body. The SI unit of momentum is kg/m/s.
Detailed explanation-2: -If two different quantities have the same unit then they must have the same dimension.
Detailed explanation-3: -The associated SI unit of force and weight is the Newton, with 1 kilogram weighing 9.8 Newtons under standard conditions on the Earth’s surface. However, in the US common units, the pound is the unit of force (and therefore weight). The pound is the widely used unit for commerce.
Detailed explanation-4: -Weight has dimensions of force or Newtons in SI units. They are related because in the earth’s gravitational field the ‘weight’ or force exerted is proportional to the mass times g, the acceleration of gravity at the earth’s surface.
Detailed explanation-5: -Thus, thrust and weight both represent the force. So they will have same unit. Was this answer helpful?
