FAQs on Mnemonics: Motion and Laws of Motion - Science & Technology for UPSC CSE

1. What are the different types of motion in physics?
Ans. In physics, motion can be categorized into several types, including: 1. <b>Translational Motion</b>: Movement from one location to another, such as a car driving down a road. 2. <b>Rotational Motion</b>: Motion around an axis, like a spinning top or the Earth rotating on its axis. 3. <b>Oscillatory Motion</b>: Back-and-forth movement around a central position, such as a pendulum swinging. 4. <b>Periodic Motion</b>: Motion that repeats at regular intervals, like a heartbeat or the motion of a clock. 5. <b>Linear Motion</b>: Movement along a straight line, which can be uniform (constant speed) or non-uniform (varying speed).
2. What are the various types of speed?
Ans. Speed can be classified into several types: 1. <b>Uniform Speed</b>: When an object covers equal distances in equal intervals of time, e.g., a train moving at a constant speed. 2. <b>Variable Speed</b>: When an object's speed changes over time, such as a car accelerating or decelerating. 3. <b>Average Speed</b>: Calculated as the total distance traveled divided by the total time taken. 4. <b>Instantaneous Speed</b>: The speed of an object at a specific moment in time, often measured using speedometers in vehicles.
3. How is velocity different from speed?
Ans. Velocity differs from speed in that it is a vector quantity, which means it has both magnitude and direction. Speed is a scalar quantity, indicating only how fast an object is moving regardless of its direction. For example, if a car is traveling at 60 km/h north, its speed is 60 km/h, but its velocity is 60 km/h north.
4. What are the different types of acceleration?
Ans. Acceleration can be categorized as follows: 1. <b>Uniform Acceleration</b>: When an object's acceleration remains constant over time, such as a freely falling object under gravity. 2. <b>Non-uniform Acceleration</b>: When an object's acceleration changes over time, like a car that speeds up and slows down in traffic. 3. <b>Centripetal Acceleration</b>: Acceleration directed towards the center of a circular path, experienced by objects moving in circular motion, such as a satellite orbiting Earth. 4. <b>Tangential Acceleration</b>: This occurs when there is a change in the speed of an object moving along a curved path.
5. What are the four fundamental forces in nature?
Ans. The four fundamental forces in nature are: 1. <b>Gravitational Force</b>: The attraction between two masses, such as the Earth and an object falling towards it. 2. <b>Electromagnetic Force</b>: This force acts between charged particles, responsible for electricity, magnetism, and light. 3. <b>Weak Nuclear Force</b>: A force that is responsible for radioactive decay and certain types of particle interactions. 4. <b>Strong Nuclear Force</b>: The force that holds protons and neutrons together in an atomic nucleus, overcoming the repulsive electromagnetic force between positively charged protons.
