Forces
Across
- 1. frictional forces are greater than the driving force
- 4. caused by a force acting on an object
- 6. motion when balanced forces are acting on a moving car
- 8. weight of a falling object is greater than air resistance
- 10. the frictional forces acting on a moving aircaft
- 12. force acting upwards on a falling object
Down
- 2. the maximum speed an object can reach when falling to Earth
- 3. resultant force when a the weight of an object is 10N downwards and air resistance is 4N upwards
- 5. unit used for weight of an object
- 7. force produced when surfaces rub together
- 9. the acceleration of an object, in m/s2, of mass 25kg when a force of 500N is applied
- 11. the force which keeps the moon in orbit around the Earth
