Communication (Short Answer - 5 marks each) Define displacement and give an example of a situation where an object can have a non-zero displacement while its distance traveled is zero. Differentiate between speed and velocity. Provide an example to illustrate the difference. Explain the meaning of the term "acceleration due to gravity" and state its approximate value on Earth's surface. Describe the motion of an object that is experiencing uniform circular motion. Mention the direction of its velocity and acceleration. Define "instantaneous velocity" and explain how it differs from average velocity
