Case Study Questions on Gravitation

Case Study Question 1

Acceleration Due to Gravity on Different Planets

Passage:
A student compares the value of acceleration due to gravity $(\mathbf{g})$ on Earth and Moon. Given:
– $g_{\text {earth }}=9.8 \mathrm{~m} / \mathrm{s}^2$
– $g_{\text {moon }}=\frac{1}{6} g_{\text {earth }}$

He drops a ball from the same height on both planets and observes different times of fall.

Q1. Which planet will show longer time of fall from the same height?
(a) Earth
(b) Moon
(c) Same on both
(d) Cannot say

Answer: (b) Moon
Explanation:

$$
t=\sqrt{\frac{2 h}{g}} \Rightarrow \text { lower } g \Rightarrow \text { higher } t
$$

Q2. If a 10 kg object weighs 98 N on Earth, what will be its weight on the Moon?
(a) 16.3 N
(b) 9.8 N
(c) 98 N
(d) 1.63 N

Answer: (a)
Explanation:

$$
W_{\text {moon }}=m g_{\text {moon }}=10 \times \frac{9.8}{6} \approx 16.3 \mathrm{~N}
$$

Q3. What happens to the mass of an object on the Moon?
(a) Increases
(b) Decreases
(c) Remains same
(d) Doubles

Answer: (c) Remains same
Explanation:
Mass is constant irrespective of location. Only weight changes due to gravity.

Q4. A ball thrown vertically on the Moon will:
(a) Rise higher than on Earth
(b) Come down faster
(c) Cover less distance
(d) Not move

Answer: (a)
Explanation:
Lower gravity → less deceleration → higher rise for same initial velocity.

We hope the given case study questions for Gravitation Class 11 helps you in your learning.
