1. Edexcel AS Physics Unit 1 : Chapter 3: Rectilinear Motion Prepared By: Shakil Raiman

2. 3.1 Speed, Velocity and Acceleration  Speed: Rate of change of distance.  Velocity: Rate of change of displacement.  Acceleration: Rate of change of velocity.  Instantaneous Velocity: Velocity at an instant.  Average speed: total distance travelled/ total time taken

3. 3.2 Equation of Motion  s = displacement or distance (m)  u = initial velocity (ms -1 )  v = final velocity (ms -1 )  a = acceleration (ms -2 )  t = time (s)  h = height (m)  g = gravitational acceleration (ms -2 )

4. 3.2 Equations of motion (Horizontal Plane)        

5. 3.3 Equations of motion (Vertical Plane- moving downward)        

6. 3.4 Equations of motion (Vertical Plane- moving upward)        

7. 3.5 Equations of Projectile motion   if air resistance is negligible  due to g the vertical part follow the equations of motion in vertical plane.

8. 3.5 Equations of Projectile motion  Flight time,  maximum height,  Range, R is max at  =45 

9. Thank You All  Wish you all very good luck and excellent result.
