Questions + Answers key
Take MCQ Physics Test1.
Define Potential energy. Write the expression of it.
2.
Define gravitational potential energy.
3.
How can an object move with zero acceleration (constant velocity) when the external force is acting on the object?
4.
Why should the object be moved at constant velocity when we define potential energy?
5.
Why does a pilot not fall down, when his aeroplane loops a vertical loops?
1.
(i) Potential energy of an object at a point P is defined as the amount of work done by an external force in moving the object at constant velocity from the point 0 (initial location) to the point P (final location).
(ii) At initial point O potential energy can be taken as zero.
(iii) Mathematically, potential energy is defined as \(U=\int { { \vec { F } }_{ a } } .\vec { dr } \)
where the limit of integration ranges from initial, location point O to final location point P.
2.
The gravitational potential energy (U) at some height h is equal to the amount of work required to take the object from ground to that height h with constant velocity.
3.
(i) It is possible when there is another force which acts exactly opposite to the external applied force.
(ii) They both cancel each other and the resulting net force becomes zero, hence the object moves with zero acceleration.
4.
(i) If the object does not move at constant velocity, then it will have different velocities at the initial and final locations.
(ii) According to work-kinetic energy theorem, the external force will impart some extra kinetic energy.
(iii) But we associate potential energy to the forces like gravitational force, spring force and coulomb force.
(iv) So the external agency should not impart any kinetic energy when the object is taken from initial to final location.
5.
At highest point of the vertical loop weight of the pilot provides the necessary centripetal force.
