Question

from the given weights find out what their weight will be on the moon and mars 72 kg and 56 kg
​

Answer 1

Being that it takes the weight of an object on earth and converts it to Martian weight, the formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2. To find the Martian weight, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2

Answer 2

Given:

Mass of a = 72 kg

Mass of b = 56 kg

To find: Weight of a and b on moon and mars

Calculation:

• Weight of any object is the force of gravity that the ground exerts on the object in the downward direction.
• Weight = m * g, where m is the mass of object and g is the gravitational acceleration of planet.
• Value of g varies with planet. On moon the value of gravitational acceleration is 1.625 m/$s^{2}$. On mars the value of gravitational acceleration is 3.72 m/$s^{2}$.

On moon:

Weight of object a on moon = 72 * 1.625 = 117 N

Weight of object b on moon = 56 * 1.625 = 91 N

On mars:

Weight of object a on mars = 72 * 3.72 = 267.84 N

Weight of object b on mars = 56 * 3.72 = 208.32 N

Answer:

Weight of mass 72 kg and 56 kg on moon are 117 N and 91 N respectively. Weight of mass 72 kg and 56 kg on mars are 267.84 N and 208.32 N respectively.
