►Type 1 Schematic diagram of elasticity

1. The little girl lifts the bucket with a force of 80 N (as shown in Figure 1-ZT-1). Please draw a schematic diagram of the force of the little girl lifting the bucket in the picture.

2. Use a force of 1000 N to pull a car at point A, diagonally to the upper right and at an angle of 30° to the horizontal direction. Please make a schematic diagram of this pulling force in Figure 1-ZT-2.

3. Draw a schematic diagram of the supporting force on a wooden block resting on the ground in Figure 1-ZT-3.

4. Draw the elastic force on the small ball in Figure 1-ZT-4 when it comes into contact with the compressed spring.

►Type 2 Schematic diagram of gravity (static object)

5. Please draw a schematic diagram of the gravity on a wooden block weighing 5 N that is stationary on a horizontal table in Figure 1-ZT-5.

6. A wooden box weighing 20 N is stationary on an incline. Please draw a schematic diagram of the gravity on the wooden box in Figure 1-ZT-6.

7. As shown in Figure 1-ZT-7, the ball is in a stationary state. Draw a schematic diagram of the gravity exerted on the ball.

8. As shown in Figure 1-ZT-8, use a thin line to pull a hydrogen balloon to a stationary state in the air. Please draw a schematic diagram of the gravity on the balloon.

9. In Figure 1-ZT-9, draw a schematic diagram of the gravity on the stationary ball A.

10. As shown in Figure 1-ZT-10, a uniform wooden rod is leaning against the wall. Please draw a schematic diagram of the gravity on the wooden rod.

►Type 3 Schematic diagram of gravity (dynamic object)

11. As shown in Figure 1-ZT-11, the football rolls on the horizontal ground. Please draw a schematic diagram of the gravity exerted by the football during the rolling process.

12. As shown in Figure 1-ZT-12, a small ball is thrown vertically upward by hand, regardless of air resistance. Please draw a schematic diagram of the force exerted on the ball during its upward movement.

13. In Figure 1-ZT-13, draw a schematic diagram of the gravity G exerted on an object decelerating and sliding up an incline with an initial velocity v.
