7. projectile motion
MOTION in two dimensions

8. What is projectile MOTION?

22. If there is no force acting on an object, then it will continue
moving at a constant speed in the same direction.
- there will be no change in its velocity
Horizontal Motion
- distance will increase the same amount with each second

23. Free Fall Revisited
An object in free fall is only acted on
by gravity
- Acceleration due to gravity is 9.8
m/s2
- distance covered increases with
each second

25. Projectile Motion Combines Vertical Motion and
Horizontal Motion
 The vertical motion of a projectile is not affected by
its horizontal motion
-meaning: The vertical motion of a projectile is
identical to an object in free fall
 The horizontal motion of a projectile is not affected
by its vertical motion
- meaning the projectile will travel the same
horizontal distance as it would if it were simply rolling
on a flat surface in the absence of friction

27. Projectile Calculations
Horizontal Distance
d = v(t)
Horizontal Velocity
vf = vi + at
Vertical Distance
d = vit + ½ gt2
Vertical Velocity
Vf = Vi + gt

28. What is the path of a projectile called?

29. Is projectile
motion one
dimensional?
No, it is 2
dimensional-
vertical and
horizontal

30. What force(s) is
acting on the
projectile?
Gravity only

31. Which direction, horizontal
or vertical has
acceleration?
Which direction, horizontal
or vertical has constant
speed?
Vertical
Horizontal
