Concepts Of Physics MCQ Edition [Volume 1]PhysicsIntroduction to Physics
Determine the dimensions of linear momentum.
Options
- AMLT⁻¹
- BML^2T⁻¹
- CML^2T⁻²
- DMLT⁻²
Correct answer
A. MLT⁻¹
Step-by-step solution
Linear momentum is defined as the product of mass and velocity. p = m v The dimensional formula for mass is [M] . The dimensional formula for velocity is [LT⁻¹] . Substituting these dimensions, we get the dimensional formula for linear momentum: [p] = [M] [LT⁻¹] = [MLT⁻¹]
