"Motion and Stillness" Mechanical Movement PPT Courseware 3

Description

"Motion and Stillness" Mechanical Movement PPT Courseware 3

learning target

1. Know the mechanical movement

2. Know the relativity between motion and stillness

3. Know what a reference object is and how to choose a reference object?

4. Be able to flexibly judge the movement of objects based on different reference objects.

1. Mechanical movement

The change in position of one object relative to another is called mechanical motion

2. Classification of mechanical motion

The motion trajectory is a straight line of motion.

The motion trajectory is the motion of the curve.

3. Reference objects

To describe whether an object is moving or stationary, you must first select a standard object as a reference. This object selected as the standard is called a reference object.

If the position of an object changes relative to the reference object, we say it is moving; if the position does not change, we say it is stationary.

What are the applications of the relativity of motion and rest?

1. Examples from sports competitions

Taking over the baton in a relay

During a marathon race, you have to hand out drinks to the athletes while running.

2. Examples from science and technology

geostationary satellite

Aircraft refueling

Two spacecraft docking in the sky

summary

motion and stillness

Mechanical motion: The change in position of one object relative to another.

Classification of sports

Straight line motion: The motion trajectory is a straight line motion.

Curved motion: The motion trajectory is a curved motion.

Reference object: an object chosen as a standard

Movement and stillness are relative.
