Questions & Step-by-Step Solutions

What is the relationship between the angular velocity and linear velocity of an object moving in a circular path?
Correct Answer: v = ωr
  • Step 1: Understand that angular velocity (ω) measures how fast something is rotating, usually in radians per second.
  • Step 2: Know that linear velocity (v) measures how fast something is moving along a circular path, usually in meters per second.
  • Step 3: Recognize that the radius (r) is the distance from the center of the circle to the object moving along the path.
  • Step 4: Use the formula v = ωr to connect linear velocity and angular velocity.
  • Step 5: This means that to find the linear velocity, you multiply the angular velocity by the radius of the circle.
