Projectile Motion PPT for STEM 12 students.ppt

This is a PPT for projectile motion for g12 STEM students

2. Question Of The Day
Trailing by two points, and with only 2.0
seconds left in the last quarter of a
basketball game, Terrence Romeo makes a
jump shot at an angle of 68 with the
⁰
horizontal giving the ball a velocity of 12 m/s.
The ball is released at the height of a basket
and it’s a score! Did Terrence tie the game
or put the team ahead?

3. Projectile Motion

4. Instructional Objectives:
Students will be able to:
Define Projectile Motion
Distinguish between the
different types of projectile
motion

5. Projectile Motion
•Two-dimensional motion of an object
–Vertical
–Horizontal

6. Types of Motion
•Horizontal
–Motion of a ball rolling freely along a level surface
–Horizontal velocity is ALWAYS constant
•Vertical
–Motion of a freely falling object
–Force due to gravity
–Vertical component of velocity changes with time
•Parabolic/ Projectile
–Path traced by an object accelerating only in the
vertical direction while moving at constant
horizontal velocity

7. Examples of
Horizontal Motion

8. Examples of Vertical
Motion

9. Factors Affecting
Projectile Motion
•What two factors would affect projectile
motion?
Angle
Initial velocity
Initial Velocity
Angle

10. Projectile Motion

11. Parts of Projectile
Motion
•Components
•Displacement and
Velocity
•Time

12. Class Exercise
An object is fired from the ground at 100 m/s
at 30 with the horizontal
⁰
a.Calculate the horizontal and vertical
components of the initial velocity
b.After 2.0 seconds, how far has the object
traveled in the horizontal direction?
c.How high is the object at this point?

16. Board Work
A long jumper leaves the ground at angle of 30
degrees to the horizontal and at a speed of 6 m/s.
How far does he jump?
Solution
