  1. Objectives of this Experience • Measure the rate at which an object travels in free-fall. • Define in your own words velocity and acceleration. • Distinguish between initial, final and average velocity. • Develop a basic understanding of vectors.

  2. Objectives of this Experience(continued) • Discover the relationship between net force, acceleration, and mass. • Name four basic forces, describe their strengths and give some examples of each. • State Newton’s Second Law, be able to use it in solving problems, and display an understanding of its application. • Incorporate the concept of gravity in utilizing Newton’s Second Law.

  3. Vectors Magnitude and Direction vector X + vector Y = vector R Head to Tail Method For example: If a plane was traveling due east at a speed of 120 mph and encountered a wind coming directly from the south, what would be the resulting speed of the airplane and in what direction would it be traveling? Resultant R y X component x y All vectors can be resolved into their x and y components.

  4. What do you remember about triangles? Pythagorean Theorem(Leg X)2 + (Leg Y)2 = (Hypotenuse R)2 Hypotenuse R R = X2 + Y2 Leg Y Note: This only applies to right triangles Leg X Similar Triangles

  5. A Little Trigonometry • Right Triangles Sine ө = opposite/hypotenuse Cosine ө = adjacent/hypotenuse Tangent ө = opposite/adjacent hypotenuse opposite ө adjacent

  6. Formulas • Average Velocity = d/t or (Vf + Vo)/2 (Vf = final velocity. Vo = initial velocity.) • Acceleration = (Vf – Vo)/t (Change in velocity/time) • F = ma (Newton’s Second Law) • Vf = √(Vo2 + 2ad) • T = √(2d/g)
