Question

Explain, in terms of the properties of the four basic forces, why people notice the gravitational force acting on their bodies if it is such a comparatively weak force.

a) Gravity acts on a large scale.
b) Gravity is stronger than other forces.
c) Gravity is invisible.
d) Gravity is the only force acting.

Answer 1

People notice the gravitational force acting on their bodies because gravity acts on a large scale and it is the only force that acts on all objects with mass.

Step-by-step explanation:

The reason why people notice the gravitational force acting on their bodies, despite it being weak compared to the other fundamental forces, is because gravity acts on a large scale and it is the only force that acts on all objects with mass. The gravitational force is always attractive, which means that it pulls objects towards one another. This force is responsible for our weight and determines much of the motion of objects in our daily lives, such as a dropped ball falling to the ground or the motion of planets and stars in astronomical systems.
