Description

"Our Little Cable Car" Movement and Power PPT

Part One: Installing a Small Cable Car

Thousands of years ago, humans invented the car. What different types of cars do we know about? What power do they rely on to move?

Carriage - the pull of a horse

Cars - engine power

Battery car-electricity

Cable car - cable tension

When we carry water, we feel the downward pull of the bucket on our hands; when we carry a schoolbag, we feel the downward pressure of the schoolbag on our shoulders. Objects all experience a downward force, which is gravity.

Our small cable car PPT, the second part: the size of the pulling force and the movement of the car

Guess how much pulling force can make the car move? How do different pulling forces affect the movement of the car?

Let's do an experiment to test the conjecture.

1. Mark the starting point and end point of the car's movement. Each experiment must start from the starting point and end at the end point.

2. Start by hanging one washer, and add washers one by one until the car can move.

3. Add more washers and observe and record how the movement of the car changes.

What did you discover through the experiment?

If the pulling force is too small, the car will not move;

When the pulling force reaches a certain level, the car starts to move;

The greater the pulling force, the faster the car moves.

discuss:

Study how forces of different sizes affect the movement of the car. Why do we need to add multiple washers?

What force pulled the car? What is the relationship between the pulling force and the movement of the car?
