BIO Spiraling Up.? Birds of prey typically rise upward on thermals. The paths these birds take may be spiral-like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume that a bird completes a circle of radius 6.00 m every 5.00 s and rises vertically at a constant rate of 3.00 m/s. Determine (a) the bird’s speed relative to the ground; (b) the bird’s acceleration (magnitude and direction); and (c) the angle between the bird’s velocity vector and the horizontal.

NEWTON’S LAWS OF MOTION 1. Objects at rest stay at rest and objects in motion stay in motion unless an outside force acts a. force changes motion b. rest feels the same as uniform motion i. you only feel changes in motion c. there’s no such thing as centrifugal force 2. Acceleration (change in motion) is directly proportional to applied force and inversely proportional to inertia (mass) a. a = f/m i. usually written as F = ma b. weight is not the same as mass c. mass is the property of an object (its inertia) d. weight = force of gravitation ON an object 3. Every action has an equal and opposite reaction a. forces always come in pairs i.
