PROJECTILES

Question 1

What is Differentiation

Answer 1

Obtaining info from another value

• up the ladder
• displacement -velocity -acceleration
• instantaneous value

Question 2

What is Integration

Answer 2

• obtaining info from another value
• putting together individual components to form a whole
• acceleration -velocity -displacement
• average value

Question 3

Vertical axis for Law of constant acceleration is affected by…

Answer 3

a= -9.81 m/s^2 only affected by gravity

Question 4

Horizontal axis of law of constant acceleration is affected by…

Answer 4

a=0m/s nothing we don’t count this in our equation because we assume no air resistance in our problems

Question 5

Why is a bird flying through the air not an example of a projectile

Answer 5

Because bird is flying horizontally, we only care about vertical

Horizaontal velocity of a projectile remains constant and only vertical velocity changes

Question 6

Is Vf always..?

Answer 6

Vf is the appex= 0 m/s

Question 7

Describe projectiles Vertical Axis

Answer 7

vertical time up= vertical time down

vertical time up= half of the horizontal time (total time)
