FAQs on 4 Days Timetable: Gravitation - Science Class 9

1. What is the law of gravitation and how does it apply to objects on Earth?
Ans. The law of gravitation, formulated by Isaac Newton, states that every mass attracts every other mass in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. On Earth, this means that all objects experience a gravitational pull towards the center of the planet, which is what gives them weight.
2. What is the difference between mass and weight?
Ans. Mass is a measure of the amount of matter in an object and is usually measured in kilograms (kg). It remains constant regardless of location. Weight, on the other hand, is the gravitational force acting on an object and is dependent on the mass of the object and the gravitational acceleration at its location. Weight can vary based on where you are in the universe, for example, an object would weigh less on the Moon than on Earth due to the Moon's weaker gravitational pull.
3. How does Archimedes' Principle explain buoyancy?
Ans. Archimedes' Principle states that any object immersed in a fluid experiences an upward force (buoyant force) equal to the weight of the fluid displaced by the object. This principle explains why objects float or sink; if the buoyant force is greater than the object's weight, it will float, whereas if it is less, the object will sink.
4. What factors affect thrust in a rocket?
Ans. Thrust in a rocket is affected by several factors, including the mass of the rocket, the speed of the exhaust gases being expelled, the angle of the rocket, and the atmospheric pressure at the launch site. The principle of action and reaction (Newton's Third Law) states that for every action, there is an equal and opposite reaction; thus, as the rocket expels gas downwards, it generates an upward thrust.
5. How can I prepare effectively for a test on gravitation and related topics?
Ans. To prepare effectively for a test on gravitation and related topics, start by reviewing the key concepts such as the law of gravitation, mass vs. weight, Archimedes' Principle, and thrust. Practice solving problems related to these concepts, and consider using diagrams to visualize concepts like buoyancy. Additionally, take practice tests to familiarize yourself with the question formats and time management during the exam.
