Week 2 Term 1 2025 Kinematics & Projectile Motion

 Homework

Kinematics

  • Act 8B Graphs of motion p.101
  • Act 8C Kinematics p.102
  • Ex 4E Kinematics p.115-117
Projectile Motion
  • Act 12B Projectile Motion p.140-141

Kinematic Equations
Only used when an object is accelerating
vf = vi + at
missing d
vf2 = vi2 + 2ad
missing t
d = vit + ½at2
missing vf
d = (vi + vf)t/2
missing a

Choose the kinematic equation based on:

  • what quantities you are given
  • what quantity is asked for
  • what quantity is not involved
