When we are standing on floor, the floor exerts reaction force on our body which we feel as our weight. If the floor itself is in free fall (eg. the elevator if the rope breaks) we don't get any reaction from the floor which is the condition of weightlessness. Mathematically reaction force, R = m(gRead more
The air resistance decreases the speed of the paratrooper while falling down and is safe. If they want to jump down in moon like this their fall will be free fall and hit the ground with more velocity which can be dangerous. On earth the atmospheric air doesn't let them to fall freely and land withRead more
The weight of any object on earth depends upon acceleration due to gravity of earth which depends upon the distance of the place from the centre of the earth. Weight decreases if the distance from centre of the earth increases. Hence the weight if less in solukhumbu compared to janakpur as the heighRead more
All the objects in this universe attract each other with a force called gravitational force. This gravitational force between any two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
When any object is at some height it has potential energy. If that object falls downward it's potential energy changes into kinetic energy. Greater the height more the kinetic energy while hitting the ground. Due to this kinetic energy the person gets injured while jumping from height.
The radius of earth is not fixed, because the earth is not perfectly spherical. At pole it's radius is shorter than the radius at equator. The weight of any object depends upon the radius of the earth and is inversely proportional to the square of the radius of the earth. Hence the weight of any obRead more
Post covid Schools should be totally different than the normal schools before. First of all the mask should be made compulsory, hands washing facility should be there for all. Class rooms shouldn't be crowded. Tiffin time shouldn't be same for all students such that they start to play or run in grouRead more
Geographically Nepal experiences active monsoon every year. The rivers are not very big in winter but terribly large during rainy season. Poor people, landless people settle near the river in city area where the risk is very high. The land developers (brokers/land mafias) make the river area very naRead more

2 second. (1 second to go up and 1 second to come down; if g = 10 m/s2) The time doesn't depend upon mass of the object.
