Terminology

Glossary

Gravitational Field: The region around a mass where it exerts a gravitational force on another mass.

Force: An interaction that changes the motion of an object.

Potential Energy: Energy stored due to an object’s position in a field.

Theory

A gravitational field is a region of space around a mass in which another mass experiences a force. The strength of the field depends on the mass of the object and the distance from it. For example, Earth’s gravitational field can be calculated using the formula:

F = G * (m1 * m2) / r²

Here, F is the gravitational force, G is the universal gravitational constant, m1 and m2 are the masses involved, and r is the distance between their centers.

Key concepts: -force-Күш, -distance-Қашықтық, and -field-Өріс.

Exercises

1. Match the terms to their definitions.
2. Calculate the gravitational force between two masses of 10kg and 15kg separated by 2m.
Solution
Using F = G * (m1 * m2) / r²:
F = 6.67 × 10⁻¹¹ * (10 * 15) / 2²
= 2.5 × 10⁻⁹ N.
