Title: Physics / Topic 2: Mechanics / 4: Projectile Motion

Q: Define: Projectile
A: Any object thrown into space upon which the only acting force is gravitational force

Q: Explain the Monkey and the Hunter analogy, draw a diagram
A: A hunter holds a rifle at the same height as a monkey, the monkey drops off the branch to avoid the bullet at the moment the bullet is fired, however, as the monkey and the bullet still fall at the same rate, the monkey is hit.

Q: How do you solve a Projectile Motion question?
A: You split the Vertical and Horizontal components of SUVAT (T is scalar)
Then you work the values out, some are known such as Ay = -9.81 and Ux=Vx as the projectile does not accelerate horizontally
Sx                             Sy = -height of fall
Ux = initial vel           Uy = usually 0
Vx = initial vel           Vy
Ax                             Ay = -9.81
T
Then you can use these to find Time as it is the same for both and you can find any missing values using SUVAT equations, as well as the angle of impact using trigonometry
