Question

If the valve of g suddenly becomes twice its value,it will become two times more difficult to pull a heavy object along the floor.why

Answer 1

If g, the acceleration due to gravity, is suddenly twice it’s value, yes, it would double the pull of an object on the floor. We commonly refer to this pull as weight.

Weight is the force of gravity on a mass. Newton's second law formula (F = ma) shows the relationship between mass, acceleration, and force. The weight formula uses Newton's second law:

w = mg

where:

w is the weight (force of gravity on a mass)m is the mass of g is the acceleration due to gravity.

Answer 2

Answer:

Explanation:

(i) If the value of g becomes double,the force with

which the earth pulls the object i.e weight of

object becomes double.

(ii) As weightincreases,frictional force also increases

while pulling the object

( iii) Hence, it will become two times more difficult to

pull a heavy object along the floor.
