"Gravity" force PPT courseware 3

learning target

1. Knowledge and skills

Know the definition of gravity.

Know the direction and center of gravity.

Through experimental exploration, understand the relationship between the magnitude of gravity and the mass of an object.

2. Process and methods

Experience the process of exploring what factors are related to the magnitude of gravity.

Try to use images to process experimental data and study experimental conclusions based on images.

1. The origin of gravity

gravity:

Between any two objects in the universe, from as large as celestial bodies to as small as dust, there is a force of mutual attraction, that is, universal gravitation.

1. The concept of gravity (G)

Gravity is represented by G, unit: N

1. The force exerted on an object due to ___________ is called gravity. All objects on Earth are affected by ____.

2. The object exerting force by gravity is: _____.

The object affected by gravity is:_______________

3. All objects near the ground are affected by gravity;

2. The size of gravity (weight)

Explore: What factors are related to the magnitude of gravity?

1. Guess what their possible situations are?

(1). The gravity exerted by an object has nothing to do with its mass?

(2) Is the gravity exerted by an object related to its mass and proportional to it? Or is it an inverse relationship?

2. Design instruments:

Spring dynamometer, hook code

Use a spring dynamometer to measure the gravity on the 50g, 100g, and 150g hook codes respectively. And fill in the corresponding form.
