Across
- 4. The force exerted by a spring is proportional to its extension, F = k*e
- 7. The energy transferred when a force moves an object, W = F*d
- 11. The attractive force between masses due to gravity.
- 16. Forces that are equal in size but opposite in direction, resulting in no change in motion.
- 19. A push or pull on an object, measured in newtons (N).
- 20. The energy stored inside a stretched object
- 21. The total distance to stop a moving vehicle, the sum of thinking and braking distances.
- 23. The distance travelled per unit of time, v = s/t
- 24. The single force that represents the combined effect of all the forces acting on an object.
- 25. The amount of matter in an object, measured in kilograms (kg).
- 27. The distance a vehicle travels after the brakes are applied until it stops.
- 28. A measure of the stiffness of a spring.
Down
- 1. The maximum velocity an object can reach when the force of gravity is balanced by the drag force.
- 2. The acceleration of an object is proportional to the resultant force acting on it, F=m*a
- 3. A quantity that has only magnitude.
- 5. An object remains at rest or in uniform motion unless acted upon by a resultant force.
- 6. For every action, there is an equal and opposite reaction.
- 8. The time taken to respond to a stimulus.
- 9. The distance a vehicle travels during the driver’s reaction time.
- 10. HIGHER The tendency of an object to resist changes to its motion.
- 12. A diagram showing all the forces acting on an object.
- 13. HIGHER The product of an object's mass and velocity, p = m*v
