Homework:
- Ex 4E, p.115-117 Kinematics (from last week)
- Ex 4F, p.119-124 Projectile Motion (from last week)
- Ex 4A, p.90-94 Vectors (from last week)
- Ex 4B, p.97-104 Forces (from last week)
- Ex 4H, p.132-134, Circular Motion
Circular Motion
- Velocity is always at a tangent to the circle. Even if the speed remains constant, the velocity is changing because it is accelerating.
vc = 2𝝿r/T
- Centrapetal Acceleration is always toward the centre of the circle.
- ac = mv2/r
- Centapetal Force is the Net Force, and is also always towards the centre of the circle.
Fc = mv2/r
Uniform Circular Motion
