"Drive the car like a rocket" Motion and force PPT download

Part One Content: Teaching Process

1. Balloon blowing competition;

2. Use balloons to drive the car;

3. Thoughts on the movement of the car.

Let go of the balloon. The balloon will move, but not in one direction, but constantly changing directions.

Why does a balloon move when it inflates? Can you control the balloon to move in one direction?

When a balloon blows out, it has a recoil force. Controlling the direction of the jet can control the direction of movement.

Balloon driven car

Experiment name: Installing and driving the trolley

Experimental equipment: balloon, practical car, balloon stopper, iron bar

Experimental steps

1. Use appropriate iron bars to install the balloon nozzle bracket; 2. Install the balloon and balloon nozzle on the bracket.

Experiment to explore why jet propels a car

Drive the car like a rocket PPT, part 2: expansion and extension

Rockets were first invented in our country. Modern rockets use high-energy substances as fuel and use liquid oxygen to assist combustion. After combustion, a large amount of high-temperature gas is produced, which is continuously ejected backward, allowing the rocket to fly at high speed.

Rockets can fly in space without air

Drive the car like a rocket PPT, Part 3: Class summary

When the gas in the balloon is ejected, it will generate a thrust in the opposite direction of the ejection, which is the recoil force. To make a stationary object move, force must be exerted on the object.

Drive the car like a rocket PPT, Part 4: Classroom training

1. Fill in the blanks

1. When the gas in the balloon is ejected, it will produce a thrust in the opposite direction to the ejection direction, which is called ( ).

2. To make a stationary object move, the object must be moved ( ).

3. Apply ( ) to the push car.

2. Choice

1. ( ) does not rely on the recoil force generated by the jet engine to move

A.jet B.rocket

C. Firecrackers D. Slingshot

2. Inflate the balloon enough and release it. The balloon will move in the direction of ( )

A.Towards one direction B.Changing direction

C.Downward D.Upward
