Question

The example of a book falling off of a table shows a(n) _____.1) contact force2) scalar quantity3) absence of acceleration4) field force

Answer 1

anotherGravity is the force of attraction between two objects. A gravitational force field is modeled as space around a massive body in which other bodies experiences force.

In Newtonian gravity, a particle of mass M creates a gravitational force field around itself given as,

`g=(GM)/(r^2)`

Here, G is the universal gravitational constant, and r is the separation between the bodies.

Hence, the example of a book falling off of a table shows a(n) field force. Therefore, option (4) is the correct choice.
