Q 4-8. A squash ball is dropped from a tall building . What are the missing words in this passage?

 squash ball
As the ball accelerates, the downwards force
of gravity on it ,
whilst the air resistance .
Eventually the two forces are .
The resultant force on the ball is now .
This means it stays at a constant speed,
called the .

9. Which of these graphs shows the velocity of the squash ball as it falls?

v-t graphs x4

10. A battery powered toy car has many forces acting on it when moving across the floor. Which of these diagrams show the correct sized arrows for the car accelerating to the right?
