Term 2 Week 5 2017

Homework

• Ex 4G, p. 153-156, Orbits - Circular Motion due to Gravity
• Ex 2A, p.19-22, Working with Errors
• Ex 2B, p. 26-37 Data Processing & Errors
• Ex 4H, p. 160-162, Rotational Motion

Radians

Radian Measure is used so that we can easily calculate an arc length, d (m), given an angle, 𝛉 (Rad) and the radius, r (m).

d = r𝛉

This in turn allows us to relate velocity, v (ms-1) to angular velocity ⍵ (rads-1), in the same way.

v = r⍵, 

also ⍵ = 2𝝅f

 This also allows us to relate acceleration, a (ms-2), to angular acceleration, α (rads-2), in the same way.

a = rα

The rotational kinematics work just like the translational kinematic equations when there is a constant acceleration.
