Questions + Answers key
Take MCQ Physics Test1.
Define weight.
2.
Why is the energy of a satellite (or any other planet) negative?
3.
Is potential energy the property of a single object? Justify.
4.
How will you prove that Earth itself is spinning?
5.
What is the difference between gravitational potential and gravitational potential energy?
1.
The weight of an object is defined as the downward force whose magnitude W is equal to the upward force that must be applied to the object to hold it at rest or at constant velocity relative to the Earth.
2.
(i) Implies that the satellite is bound to the Earth and it cannot escape from the Earth
(ii) As h approaches ∝ the total energy tends to zero. Its physical meaning is that the satellite is completely free from the influence of Earth's gravity and is not bound to Earth at large distances.
3.
No, potential energy is not the property of a single object. But, it is the gravitational potential energy of the system consisting of two masses m1 and m2 separated by a distance r, is the gravitational potential energy difference of the system when the masses are separated by an infinite distance and by distance r.
\(\mathrm{U}(\mathrm{r}) =\mathrm{U}(\mathrm{r})-\mathrm{U}(\alpha)
\)
\(\therefore \mathrm{U}(\alpha) =0\)
4.
Due to Earth's spinning motion, the stars in sky appear to move in circular motion about the pole star.
5.
| S.No | Gravitational potential | Gravitational potential energy |
| 1. | It depends only on the source mass. | It depends upon two masses and the distance between them. |
| 2. | It is a scalar | It is a scalar |
| 3. | It's unit is J Kg-1. | Its unit is Joule. |
