"Exam in this Chapter" Power PPT

1. (Jiaxing High School Entrance Examination) On May 21, 2018, my country's Long March 4C carrier rocket successfully carried the "Queqiao" relay satellite into space. After the carrier rocket was ignited, the rocket ejected gas downwards and gained upward power. To accelerate into the air, the force-applying object of this power is gas.

2. (Suihua High School Entrance Examination) As shown in the figure, when the springboard is bent by a diver, the object exerting force is the athlete; this phenomenon shows that force can change the shape of the object.

3. (Zhenjiang High School Entrance Examination) In the picture, the spring dynamometer indicates 2.8 N.

4. (Beijing High School Entrance Examination) In the experiment shown in the figure, the small iron ball is released from the top of the inclined plane from rest, and its trajectory on the horizontal table is observed as shown by the dotted line OA in Figure A. Place a magnet on the side in the OA direction, release the small iron ball from the top of the incline from rest, and observe its trajectory on the horizontal table as shown by the dotted line OB in Figure B. The conclusion that can be drawn from the above experimental phenomena is (C)

A. The small iron ball continues to move on the table due to the forward force it receives.

B. The magnet has no force on the small iron ball

C. Force can change the motion state of the small iron ball

D. Force can deform the small iron ball

5. (Hangzhou High School Entrance Examination) The picture shows the trajectory of a thrown medicine ball. The force (B) experienced by the highest point of the medicine ball during its flight in the air after leaving the hand

A. Only gravity

B. Gravity and air resistance

C. Gravity and hand push

D. Gravity, air resistance and hand push
