Week 8 - Projectile Motion Flashcards
1
Q
Describe projectile motion
A
How a point or body moves when airborne
2
Q
Describe parabolic flight path
A
No horizontal force or acceleration
Gravity as vertical force with acceleration of -9.81m/s^2
3
Q
What factors affect projectile range
A
Release speed
Release angle
Release height
4
Q
How do we increase range of projectile motion
A
Greater release speed
Optimum angle 45 degrees
Greater release height
5
Q
What is tangential release
A
If a body moves in a circle and is released, angle equals the tangent to the circle
6
Q
What are the steps to solving projectile motion problems
A
Separate into vertical and horizontal components
Solve for either with info available
Apply correct constant equation for unknown
Use one component to solve the other
Check its sensible
