Exam 2 - 304

Linear Motion

1. Term: Linear Distance
   Definition: Total path length traveled, measured in meters or kilometers.

2. Term: Displacement
   Definition: Straight-line distance from start to end, including direction.

3. Term: Speed
   Definition: Rate of covering distance (distance per unit time).

4. Term: Pace
   Definition: Time taken to cover a unit of distance (e.g., minutes per km).

5. Term: Velocity
   Definition: Rate of change of position, including direction.

6. Term: Acceleration
   Definition: Rate of change of velocity over time.

Angular Motion

7. Term: Angular Distance
   Definition: Total angle rotated, measured in degrees or radians.

8. Term: Angular Displacement
   Definition: Smallest angle between start and end positions, with direction.

9. Term: Angular Speed
   Definition: Rate of rotation (angle per unit time).

10. Term: Angular Velocity
    Definition: Rate of change of angular displacement, with direction.

11. Term: Angular Acceleration
    Definition: Rate of change of angular velocity over time.

Relationships Between Linear and Angular Motion

12. Term: Relationships Between Linear and Angular Motion
    Definition: Connection between rotation and straight-line motion (v=rωv=rω).

Kinematics of Projectile Motion

13. Term: Kinematics of Projectile Motion
    Definition: Study of motion of objects launched into the air under gravity.

14. Term: Factors That Influence Projectile Motion
    Definition: Initial speed, launch angle, air resistance, and gravity.

15. Term: Optimal Conditions for Projectiles
    Definition: 45° launch angle for maximum range (no air resistance).

16. Term: Horizontal and Vertical Components
    Definition: Breakdown of motion into horizontal (constant) and vertical (accelerated) parts.

Trigonometry Basics

17. Term: Pythagorean Theorem
    Definition: In a right triangle, a2+b2=c2a2+b2=c2.

18. Term: SOHCAHTOA
    Definition: Sine = opposite/hypotenuse, cosine = adjacent/hypotenuse, tangent = opposite/adjacent.

Vector Algebra Basics

19. Term: Vector Composition
    Definition: Combining vectors to produce a resultant vector.

20. Term: Vector Resolution
    Definition: Breaking a vector into horizontal and vertical components.

21. Term: Tip to Tail Method
    Definition: Adding vectors by placing the tail of one at the tip of another.
