Problem 14Q

Problem

Compare the effort (or force) needed to lift a 10-kg object when you are on the Moon with the force needed to lift it on Earth. Compare the force needed to throw a 2-kg object horizontally with a given speed on the Moon and on Earth.

Solution 14Q:

We have to find whether there is any difference in force (or effort) required to lift same object on Earth and Moon.

Step 1 of 3

Concept:

Newton’s second law: The force F acts on mass m produces an acceleration a in the object. Mathematically, F=ma.

Force acting on an object (Weight) in the vertically downward direction due to the gravitation pull of the planet is given as, F=mg, where m is the mass of the object and g is the acceleration due to gravity.

Value of acceleration due to gravity of earth is six times the value of acceleration due to gravity of moon.
