ملخص الدرس

This lesson introduces the concept of gravitational force, a fundamental field force that acts at a distance. It distinguishes between contact forces and field forces, and explores the characteristics of Earth's gravitational field. The lesson also explains the universal nature of gravity, how it affects all objects, and the difference between mass and weight, including the relationship W = mg.

هتتعلم إيه فى الدرس ده

• Gravitational force is a field force that acts at a distance and attracts all objects towards the center of the Earth.
• Contact forces require physical contact, while field forces act over a distance.
• Gravitational force between two objects increases with mass and decreases with distance.
• Mass is the amount of matter in an object, while weight is the gravitational force acting on it.
• Weight (W) is calculated by multiplying mass (m) by the gravitational field intensity (g), where W = mg.
