Chapter 3

Question 1

Component

Answer 1

-Describes the affect of a single vector in a given direction

Question 2

Distance equation

Answer 2

D= square root of x^2 + y^2

Question 3

Curvilinear motion

Answer 3

-Motion that occurs when an object travels along a curved path

Question 4

Projectile Motion

Answer 4

-the curved path that an object follows when thrown, or otherwise projected near the surface of the earth

Question 5

Projectile

Answer 5

• Any object launched into the air that is subjected to gravity
  
  • An object dropped from rest
  • Object thrown vertically upwards
  • Object thrown upwards at an angle
• Follow a curved path called a parabola
• Horizontal velocity for projectiles is constant due to neglected air resistance

Question 6

Types of Projectiles

Answer 6

• Horizontal projectiles: Initially thrown horizontally

- Angle projectiles: Starts on both X and Y axis

Question 7

Objects Projected Horizontally

Answer 7

• Initial velocity= final velocity
• Initial Vy= 0m/s (becomes more negative over time)
• No acceleration

Question 8

Projectile Points of Interest

Answer 8

• Time of flight (time is shared between X and y)
• Maximum heigh: reached when velocity is 0)
• Range: maximum x (horizontal) value traveled
