Random: Off 1. What is the SI unit of work? ⓐ. Joule ⓑ. Newton ⓒ. Watt ⓓ. Erg Explanation: The SI unit of work is the joule, defined as the amount of work done when a force of one newton displaces an object by one meter in the direction of the force. 2. Which of […]
Random: Off 1. According to Newton’s first law of motion, an object at rest tends to stay at rest, and an object in motion tends to stay in motion with uniform velocity unless acted upon by an external force. Which of the following statements best describes this law? ⓐ. Objects always remain at rest unless
Random: Off 1. Which of the following is a scalar quantity? ⓐ. Displacement ⓑ. Velocity ⓒ. Speed ⓓ. Acceleration Explanation: Speed is a scalar quantity as it only has magnitude and no direction. Displacement, velocity, and acceleration are vector quantities, meaning they have both magnitude and direction. 2. What is the SI unit of displacement?
Random: Off 1. Which of the following quantities is a vector quantity? ⓐ. Speed ⓑ. Distance ⓒ. Velocity ⓓ. Mass Explanation: Velocity is a vector quantity because it has both magnitude and direction, unlike speed, which is a scalar quantity and only has magnitude. Distance and mass are also scalar quantities. 2. Which of the
Random: Off 1. Which of the following is a base quantity in the International System of Units (SI)? ⓐ. Volume ⓑ. Mass ⓒ. Speed ⓓ. Force Explanation: In the International System of Units (SI), mass is considered a base quantity. The base unit for mass in the SI system is the kilogram. Volume, speed, and
Random: Off 1. What is the primary objective of physics? ⓐ. To understand the functioning of the human body ⓑ. To study celestial bodies ⓒ. To understand the laws of nature and their interrelationships ⓓ. To develop new languages Explanation: The primary objective of physics is to gain a deep understanding of the fundamental laws
