Chapter 3 Projectile Motion Concepts

Question 0

Describe the horizontal motion if projectiles

Answer 0

Constant horizontal velocity
Independent of vertical velocity
Horizontal displacement depends on the time of flight and initial horizontal velocity
Final horizontal v = initial v
As launch speed increases, so does horizontal displacement

Question 1

What are the requirements for an object to be a projectile

Answer 1

Free falling object
Must be accelerating in the downward direction
Could begin it’s motion with a downward velocity

Question 2

Describe vertical motion if projectiles

Answer 2

Changes at constant rate
Has continuous downward a
Magnitude changes by 9.8m/s
Vertical v is 0m/s at peak of trajectory
Peak height depends on initial vertical velocity
Peak height always increases when launch angle increase btw 0 and 90
Peak height increases as launch speed increases
