Q
Q: A particle is moving in a straight line with a velocity v. What is its angular momentum about a point O located at a distance r from the line of motion?
Solution: Angular momentum L = mvr, where r is the perpendicular distance from the line of motion to point O.
Steps: 5
Step 1: Understand that angular momentum is a measure of how much motion a particle has around a point.
Step 2: Identify the particle's mass (m) and its velocity (v) as it moves in a straight line.
Step 3: Determine the distance (r) from the line of motion to the point O where you want to calculate the angular momentum.
Step 4: Recognize that the formula for angular momentum (L) is L = mvr.
Step 5: Use the values of mass (m), velocity (v), and the perpendicular distance (r) to calculate the angular momentum.
