Projectile motion

Question 1

What is the definition of projectile motion?

Answer 1

the motion of an object or the human body being projected into the air at an angle

Question 2

What are the 3 factors that affect the displacement of a projectile (how far it travels?

Answer 2

• Velocity (the greater the velocity, the further it travels)
• Height of release (the higher the object is released the further it will go
• Angle of release (there is an OPTIMAL angle for release

Question 3

What two factors affect the angle of release?

Answer 3

1) Height of release

2) Landing height

Question 4

What is the optimal angle for Long jump, Shot putt and a basketball free throw?

Answer 4

Long jump = 45
BBFT = >45
Shot put =

Question 5

What are the 2 types of flight paths?

Answer 5

1) Parabolic (symmetrical)

2) Distorted parabolic (asymmetrical)

Question 6

What factors affect an object having a distorted or parabolic flight path?

Answer 6

If the object is largely affected by AR then it will have a distorted flight path. Objects with a large weights aren’t affected by AR and so will have a parabolic flight path

Question 7

Explain the flight path of a shot putt…

Answer 7

• Because the object has high weight, AR doesn’t need to be considered due to its large mass/inertia
• It will enter a state of momentum (momentum is constant) until an external force is applied upon it
• Therefore it has a parabolic flight path
• The height of release must be less than 45
• The vertical components (action force) turns into horizontal components due to gravity
