Projectile Motion

Question 1

3 factors that affect projectile motion?

Answer 1

Height
Speed
Angle
of release

Question 2

When would you want to release the object at an angle greater than 45 degrees?

Answer 2

Release is below the landing point

Question 3

When would you want to release the object at an angle less than 45 degrees?

Answer 3

Release is above the landing point

Question 4

What is a parabola?

Answer 4

Path of a projectile with interference taken into account

Question 5

What 2 forces affect a projectile in flight?

Answer 5

Weight

Air resistance

Question 6

What are the 2 components of parabolic flight?

Answer 6

Vertical and horizontal

Question 7

What is the vertical component of parabolic flight affected by?

Answer 7

Gravity

Question 8

What is the horizontal component of parabolic flight affected by?

Answer 8

Remains constant

Question 9

When you draw vector components of parabolic flight, what do you need to remember is important?

Answer 9

Size of arrows!

They are proportional to each other.

Question 10

Explain the flight path of a heavy object.

Shot put

Answer 10

Landing height is below release height.
Hand height to foot height
Symmetrical bc no AR bc weight is dominant
Parabolic flight path because weight is dominant

Question 11

Explain the flight path of a light object.

Shuttlecock

Answer 11

Landing height is below release height
AR is dominant due to small weight
Asymmetrical flight- quick drop off
Non-parabolic
Asymmetrical because dominant AR

Question 12

What does parabolic flight mean?

Answer 12

True arc- symmetrical
