Question

compare and calculate mass and weight of ram on the earth and the moon if the body mass of ram is 60 kg​

Answer 1

We have,

Body mass of the ram (m) = $60 kg$

∴ The ram's mass on the moon =  $60 kg$ (∵ mass remains constant throughout the universe)

Similarly, the ram's mass on Earth =  $60 kg$

Now, we know that weight is actually a measure of force, thus it is different from the concept of mass

This means, Weight (W) = Force (F)

⇒ W = mass (m) × acceleration due to gravity (a) = ma

∴ Ram's weight on Earth = ma  = $40kg$ × $9.8m/s^2$  = $392$ $kg.m/s^2$ = $392$ N (∵ W = F)

Now, the ram's weight on Moon = $\frac{1}{6}$ (Ram's weight on Earth) = $\frac{1}{6}$ × $392$ N = $65.33$ N

Ans) Mass of the ram on Earth = 60 kg

Mass of the ram on the moon = 60 kg

Weight of the ram on Earth = 392 N

Weight of the ram on the moon = 65.33 N
