1. Learning Outcomes
Most are able to explain and justify the theory of projectile motion to a number of sports.
Some are able to predict the factors that affect projectile motion.

2. Homework Flipped learning activity on Angular motion.
Complete exam questions on projectile motion
Ensure you meet with the relevant person to discuss coursework

3. Flight of a projectile STARTER 1 : Group work on exam feedback
STARTER 2: Using the whiteboards explain the flight of
Shot
Table tennis ball
Justify the shape of the curve.
Extension : predict factors that affect the distance the projectile covers.

4. Projectile Motion
This refers to the motion of either an object or the human body being ‘projected’ into the air at an angle.
The flight path is called a trajectory.
Examples in sport:
a ball as a projectile
long jump (human body as a projectile)
gymnastic vault (human body as a projectile)

5. Factors affecting the shape of the curve
Red = vertical component
Blue = horizontal component
Gravity and Air resistance affect the vertical component

6. Parabolic Flight Curve

7. Parabolic Flight Curve
Effects of air resistance minimal on horizontal component
Weight predominant force on vertical component
Applies to most sport projectiles
Symmetrical flight path

8. Distorted Parabolic Flight Curve

9. Distorted Parabolic Flight Curve
Air resistance causes projectile to veer away (little weight)
Asymmetrical
Badminton/Golf Ball
Badminton
Struck hard – AR very large, resultant force close to air resistance, first part of flight slow
Later in flight – AR much less

10. Mini plenary Write either a sentence, four words or
draw a diagram and label (AR and Weight)
to illustrate your understanding of the differences in the shape of the flight curve of a SHOT PUT and a TABLE TENNIS

Table Tennis Ball (distorted parabolic)

12. Factors affecting distance
Activity:
Predict factors that affect the distance covered by the projectile by using the equipment provided.
Factors to consider:
Angle of release Height of release
Velocity of release Landing height

13. Factors affecting distance
Height of release
Increase leads to an increase in the horizontal displacement (distance) of the projectile.
e.g. Taller shot putters have an advantage over shorter ones
Velocity of release
e.g. the shift in shot putt is to ensure that the shot leaves the performers hand at maximum velocity

14. Factors affecting distance
Angle of release
for any given velocity and
height of release, there is an
optimal release angle which
maximises the horizontal
Displacement.
When both the release height and the landing height are equal then the optimum angle of release is 45o.

15. Factors affecting distance
Landing height
If the release height is greater than the landing height, the optimum angle of release needs to be less than 45o.
E.g. shot putt.
If the release height is below the landing height then the optimum angle of release needs to be greater than 45o.
E.g. Shooting in basketball (assuming the ring is the landing height).
