Question

how does gravity cause the solar system to move within the galaxy? write here...

Explanation:

Gravity is a fundamental force. In a galaxy, there is a large amount of mass (including stars, gas, dust, and dark matter). The gravitational pull of all this mass acts on the solar system. Just like the gravitational pull of the Sun keeps the planets in orbit around it in the solar system, the combined gravitational influence of the galaxy's mass causes the solar system to move along a particular path (orbit) within the galaxy. The distribution of mass in the galaxy determines the nature of this gravitational pull and thus the motion of the solar system.

Answer:

Gravity from the galaxy's mass (stars, gas, dust, dark matter) pulls the solar system, making it move along an orbit within the galaxy.
