P2.2 Forces

1. The force of attraction between all objects. The more mass an object has, the larger this force is exerted. (7)
4. This is proportional to the force applied up to a limit but above that limit it is not proportional to the force. (9)
5. The single force that would make an object move in exactly the same way as all the original forces acting together. (9, 5)
10. Forces in the opposite direction to motion and increase when the object moves faster. (4, 6)

2. The maximum speed of an object, reached when the forces moving the object are balanced by it's frictional forces. (8, 8)
3. A frictional force acting in the opposite direction to the movement of the object. (3, 10)
6. A push or a pull. This is measured in newtons. (5)
7. The amount of matter an object contains which is measured in kg. (4)
8. Force that resists one object moving through or over something. (10, 6)
9. This is the time taken for the driver to react to a hazard. (8, 4)
