3.4.1.3 Motion along a straight line
| Content | Opportunities for skills development |
|---|---|
Displacement, speed, velocity, acceleration. |
Calculations may include average and instantaneous speeds and velocities.
Representation by graphical methods of uniform and non-uniform acceleration.
Significance of areas of velocity–time and acceleration– time graphs and gradients of displacement–time and velocity–time graphs for uniform and non-uniform acceleration eg graphs for motion of bouncing ball.
Equations for uniform acceleration:
Acceleration due to gravity, g.
MS 3.6, 3.7 / PS 1.1, 3.1 Distinguish between instantaneous velocity and average velocity. MS 3.5, 3.6 Measurements and calculations from displacement–time, velocity–time and acceleration–time graphs. MS 0.5, 2.2, 2.3, 2.4 Calculations involving motion in a straight line. |
Required practical 3: Determination of g by a freefall method. | MS 0.3, 1.2, 3.7 / AT d Students should be able to identify random and systematic errors in the experiment and suggest ways to remove them. MS 3.9 Determine g from a graph. |
