Ch 6: Circular Motion 1

1. Development

2. Overview// Cases:

Forces 3

4. Object on an incline plane
4.1.     Object on incline plane experiences 3 forces: Normal force (N), gravitational force (W) and friction (f)

4.2 FBD

4.3 Transform

4.4 Forces in equilibrium

SF_nett = 0  Þ SF_x = 0

Þ SF_y = 0

Forces 2

3. Newton's Law

3.1 Newton's 1st Law is about object in equilibrium

- Object at rest will stay at rest, or continue to move with constant velocity in a straight line unless it is acted upon by an external force

Forces 1

1. Type of forces

2. FBD, example 1

- Below is a flying jet

- Label all the forces that act on it

- Draw FBD

Momentum & Impulse 2

3.2 Conservation of linear momentum

1. States

• “In an isolated (closed) system, the total momentum of that system is constant.”

OR

• “When the net external force on a system is zero, the total momentum of that system is constant.”, Sp = constant,

OR

•  The total of initial momentum = the total of final momentum

Sp_i = Sp_f

2. In 2-D Þ Sp_ix = Sp_fx
                 Þ Sp_iy = Sp_fy

3. Type of collission

# Use to determine either it's elastic or inelastic collision
