A
inertia
B
gravity
C
friction
D
spring
Explanation: 

Detailed explanation-1: -Gravitational force is the force due to which all the planets revolve around the Sun. This force of attraction exists between any two bodies in the universe that have mass.

Detailed explanation-2: -Gravity is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth’s surface. Planets have measurable properties, such as size, mass, density, and composition. A planet’s size and mass determines its gravitational pull.

Detailed explanation-3: -E.g. the planets and comets experience an attractive force towards the Sun. Moons and artificial satellites are attracted to their planets, and so are pulled towards them. This gravitational force keeps them moving in curved paths called orbits.

Detailed explanation-4: -Therefore, the force of gravitation between the earth and the sun is 3.57 × 10 22 N .
