Interactive science worksheet for Year 2 students exploring the effects of forces, including movement, direction, and shape changes.

Problem Analysis:

The task is to fill in the blanks with the correct words from the given options: *direction*, *shape*, *stop*, *start*, *speed up*, and *slow down*. Each blank corresponds to a statement about what forces can do to objects. The images provided next to each statement give clues about the correct word to use.

Solution:

#### 1. A force can ______ an object to move.
- Clue: The image shows a person kicking a soccer ball, which starts moving.
- Correct Word: *start*
- Explanation: A force (in this case, the kick) causes the ball to start moving from rest.

#### 2. A force can make a moving object ______.
- Clue: The image shows a squirrel catching a nut, which implies stopping the motion of the nut.
- Correct Word: *stop*
- Explanation: The squirrel's hand applies a force to stop the nut's motion.

#### 3. A force can change the ______ of a moving object.
- Clue: The image shows a green ball changing its path, indicating a change in direction.
- Correct Word: *direction*
- Explanation: A force can cause a moving object to change its direction of motion.

#### 4. A force can change an object ______.
- Clue: The image shows a hand squeezing a stress ball, which changes its shape.
- Correct Word: *shape*
- Explanation: A force applied to an object can deform or change its shape.

#### 5. A force can ______ an object.
- Clue: The image shows a bicycle slowing down, indicating a reduction in speed.
- Correct Word: *slow down*
- Explanation: A force (such as friction or braking) can reduce the speed of a moving object.

#### 6. A force can ______ an object.
- Clue: The image shows a car accelerating, indicating an increase in speed.
- Correct Word: *speed up*
- Explanation: A force (such as the engine's thrust) can increase the speed of a moving object.

Final Answer:

1. start
2. stop
3. direction
4. shape
5. slow down
6. speed up
