Across
- 9. A change in velocity over time
- 10. For every action there is an equal and opposite ........
- 11. This is when a number of forces acting can be 'resolved' into just one acting on the object.
- 12. When the forces are like this there is constant velocity
Down
- 1. Distance divided by time
- 2. Unit of force
- 3. This is mass times acceleration
- 4. This is a magnitude and a direction (examples are Velocity, forces, acceleration)
- 5. the unit of mass
- 6. This is a velocity where the forces are balanced (air resistance matched by weight or thrust)
- 7. This speed is represented by a horizontal line on a velocity / time graph.
- 8. Newton's 1st law is sometimes called this law.
