Projectile motion Flashcards
1
Q
What is a projectile
A
- body projected into the air or dropped from a height
- only influenced by air and gravity
2
Q
what factors govern projectile motion
A
3
Q
why is a flying bird not a projectile?
A
Because it can intentionally change its course
4
Q

Q
List an example of a sport or situation in which minimizing a projectile’s time in the air is important.
A
6
Q
How do athletes or performers affect the flight path of a projectile?
A
7
Q
terminal velocity, why this happen?
A
terminal velocity when the system reaches a constant velocity in free fall because acceleration due to gravity and air resistance equal each other. Projected area influences terminal velocity
8
Q
projected area
A
the area exposed in the direction of projectile or where airflow hits, influences drag
