Forces
under construction
The various syllabus statements cover very different quantities of material. I'm sorry there aren't any pictures yet. You may need to read this page in conjunction with block 1 of the syllabus specification. xxx represents a page number in England, (3rd edition).
| 1 |
use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second2 , (m/s2 ), newton (N), second (s) 26-27 |
| 2 | understand and use distance - time graphs 26-27 |
| 3 |
recall and use the relationship between average speed, distance moved and time average speed = distance moved / time taken 26-27 |
| 4 |
recall and use the relationship between acceleration, velocity and time acceleration = change in velocity / time taken 26-27 |
| 5 |
interpret velocity - time graphs 42-43 |
| 6 |
determine acceleration from the gradient of a velocity - time graph and the distance travelled from the area between the graph and the time axis. 42-43 |
| 7 |
express a force as a push or pull of one body on another. 4-5 |
| 8 |
identify various types of force (e.g. gravitational, electrostatic etc) 4-5 |
| 9 |
distinguish between vector and scalar quantities 20-21 |
| 10 |
appreciate the vector nature of a force 20-21 |
| 11 |
add forces that act along a line. 20-21 |
| 12 |
understand that friction and drag are forces that opposes motion. 4-5, 33-34 |
| 13 |
recall and use the relationship between unbalanced force, mass and acceleration force = mass × acceleration 36-37 |
| 14 |
recall and use the relationship between weight, mass and g : weight = mass × g 38-39 |
| 15 |
describe the forces acting on falling objects and explain why falling objects reach a terminal velocity 38-39 |
| 16 |
describe the factors affecting vehicle stopping distance including speed, mass, road condition and reaction time. 102-103 |
| 17 |
recall and use the relationship between the moment of a force and its distance from the pivot: moment = force × perpendicular distance from pivot 14-15 |
| 18 |
recall that the weight of a body acts through its centre of gravity. 16-17 |
| 19 |
recall and use the principle of moments for a simple system of parallel forces acting in one plane 14-15 |
| 20 |
understand that the upward forces on a light beam supported at its ends vary with the position of a heavy object placed on the beam. 14-15 |
| 21 |
describe how extension varies with applied force for helical springs, metal wires and rubber bands. 12-13 |
| 22 |
recall that the initial linear region of a force - extension graph is associated with Hooke’s law. 12-13 |
