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.

Step-by-Step Solution:

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 </p>

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.

Step 2 of 3</p>

Weight of an object on the Earth surface is , the weight of the same object on the Moon surface is  

Hence, it would be comparatively six times more easier to lift the same object on Moon surface.

Therefore, the effort to lift any object on the Moon Surface is 6 times less than that required on the Earth surface to lift the same object.
