Yr13 🟠 4.3 Projectile Motion

Question 1

What is projectile motion

Answer 1

The movement of either an object or the human body as they travel through the air

Question 2

What factors affect the horizontal displacement of a projectile

Answer 2

Angle of release
Speed of release
Height of release

Question 3

What is the optimum angle of release for a world class shot putter

Answer 3

From 26 degrees to 38 degrees

Question 4

How does speed of release affect horizontal displacement

Answer 4

The greater the release velocity of a projectile, the greater the horizontal displacement travelled

Question 5

How does height of release affect horizontal displacement

Answer 5

A greater release height also results in an increase in horizontal displacement as the force of gravity takes longer to pull it down

Question 6

What are the factors affecting flight paths of different projectiles

Answer 6

Weight and air resistance

Question 7

What is a parabola

Answer 7

A uniform curve that is symmetrical at its highest point

Question 8

What is the difference between a shotput and a shuttlecock in terms of their parabola

Answer 8

A shotput is a true parabola whilst a shuttlecock has a distorted parabola due to it being more heavily affected by air resistance

Question 9

What are the two vector components of parabolic flight

Answer 9

Horizontal component
Vertical component

Question 10

Relationship between optimal angle of release, release height and landing height

Answer 10

When the release height and landing height are equal ( e.g long jump) then the optimal angle of release is 45°

When release height is below landing height (e.g basketball shot) then the optimal angle of release is greater than 45°

When the release height is greater than the landing height (e.g shot put) then the optimal angle of release is less than 45°

Question 11

Horizontal displacement

Answer 11

the shortest distance from starting to finishing in a line parallel to the ground

Question 12

Horizontal component of parabolic flight

Answer 12

the horizontal motion of an object

Question 13

vertical component of parabolic flight

Answer 13

the upward motion. of an object
