Q3.3: NCERT Physics - Part 1 MOTION IN A PLANE 3.3 Solution: Pick out the only vector quantity in the following list:…
⚠️ Common Exam Traps & Conceptual Pitfalls
Students often think impulse is a scalar because it is the product of force and time, but a scalar times a vector remains a vector. The impulse is the change in momentum vector, $mathbf{J}=mathbf{F}Delta t=Deltamathbf{p}$, so its direction matters. Treat impulse as a vector, not a scalar magnitude.
Pick out the only vector quantity in the following list: Temperature, pressure, impulse, time, power, total path length, energy, gravitational potential, coefficient of friction, charge.
Step-by-Step Verified Solution
**Answer:** Impulse.
**Step-by-Step Explanation:**
Impulse is the product of force (vector) and time (scalar), giving a vector. All other quantities listed are scalars. [citation:1]
