Detailed explanation-1: -Force means the force of gravity between the Earth and an object. Mass means the mass of the object (how much space it takes up). Earth’s gravity means the Earth’s constant gravity which is 9.8 newtons per kilogram (N/kg).
Detailed explanation-2: -The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length-symbol m. The kilogram, unit of mass-symbol kg.
Detailed explanation-3: -gravity force is measured in newtons (N) mass is measured in kilograms (kg) gravitational field strength (g) is measured in newtons per kilogram (N/kg)
Detailed explanation-4: -5.2. In 1728, Newton demonstrated the universality of the force of gravity with his cannonball thought-experiment. Here Newton imagined a cannon on top of a mountain. Without gravity, the cannonball should move in a straight line. If gravity is present, then its path will depend on its velocity.
