Physics Module 3

Physics Module 3

1. 3.1 Motion

   • Displacement/Time Graphs
     • velocity = displacement/time
   • Velocity/Time Graphs
     • Acceleration = Velocity/Time
   • Problem Solving (Projectiles)
     • General Points:
       • The strategy is to consider the horizontal and vertical components of the motion separately, and use the equations of motion in each direction.
       • • The vertical acceleration is always -9.81 ms-2 (due to gravity)
       • • The projectile will continue to move upwards until the vertical component of its velocity is zero • The horizontal acceleration is always zero • The horizontal velocity is constant
     • Stratagies

2. 3.2 Forces in Action

3. 3.3 Work, Energy and Power

4. 3.4 Materials

5. 3.5 Momentum
