Projectile Motion

Question 1

3 factors affecting horizontal displacement of a projectile

Answer 1

–Angle of release
–Speed of release
–Height of release

Question 2

Example of when release height is equal to landing height

Answer 2

Long jump, 45° angle

Question 3

Example of when release height is below landing height

Answer 3

Shot in basketball, greater than 45°angle

Question 4

Example of when release height is greater than landing height

Answer 4

Shot put, less than 45°angle

Question 5

How does speed of release affect horizontal displacement of a projectile

Answer 5

The greater the release velocity if projectile, the greater the horizontal displacement travelled

Question 6

Example of How speed of release affect horizontal displacement of a projectile

Answer 6

Shot put, the speed of rotation across the circle, ensures that the shot leaves hand at maximum velocity so a greater horizontal displacement can be achieved

Question 7

How does Height of release affect horizontal displacement of a projectile

Answer 7

A greater release height leads to an increase in horizontal displacement.

Question 8

Define parabola

Answer 8

A curve with matching left and right sides

Question 9

How does weight affect flight paths of different projectiles

Answer 9

Projectiles with large weight have small air resistance force and follow a true parabolic flight path
E.g. shot put

Question 10

How does air resistance affect the flight paths of different projectiles

Answer 10

The longer the flight paths, the longer air resistance can affect a projectile
