Using the analogy of a trampoline, it becomes easier to understand how a planet distorts spacetime and how this explains the moon orbiting the Earth. Imagine a large trampoline stretched out flat, representing the fabric of spacetime.
When a heavy object, like a planet, is placed on the trampoline, it creates a depression or a curvature in the fabric. This represents the distortion of spacetime caused by the planet's mass. The greater the mass of the planet, the deeper the curvature.
Now, if you place a smaller object, like a smaller ball or a marble, on the trampoline, it will naturally roll towards the larger object due to the curvature created by it. This movement is similar to how gravity works.
In this analogy, the Earth represents the heavy object (planet), and the moon represents the smaller object (marble). The Earth's mass distorts the spacetime around it, creating a curvature. As a result, the moon follows a curved path around the Earth, rather than moving in a straight line. This curved path of the moon's orbit is due to the gravitational pull of the Earth.
Essentially, the analogy of a trampoline helps to visualize how the distortion of spacetime created by a planet's mass affects the motion of objects around it.

short answer
The trampoline analogy explains how a planet distorts spacetime and how this causes objects like the moon to orbit around it. The planet's mass creates a curvature in spacetime, and objects near the planet, like the moon, follow a curved path due to this distortion, similar to how a small ball would roll towards a depression on a trampoline.
two sentence answer?
Planets distort spacetime due to their mass, creating a curved path in which objects like the moon orbit around them, similar to how a ball would roll towards a depression on a trampoline.
