Lesson: 1.5 Applications: Angular and Linear Velocity Part 2 Goal: Solve problems involving linear velocity DOD From last time. .. Angular Displacement: angle of movement ± ²³´µ¶·¸¹µº» ¼ ½¾ Angular Velocity: angular displacement per unit of time. ¿ ± À Á ¿Â à ĵųÆÇÄ È ± angular velocity Units are usually rpm (revolutions per minute) or rad/sec (radians per second). Linear Velocity: linear distance traveled per unit of time. É ± ¿² É ± Linear Velocity ¿Â à ĵųÆÇÄ È ± angular velocity ² ± radius Notice that we will need to find angular velocity to find linear velocity ! _______________________________________ Examples The wheel of a car is turning at 15 rps (revolutions per second). The wheel has a radius
