FAQs on Quick Revision: Motion Video Lecture - Science Class 9

1. What is motion in physics?
Ans. Motion in physics is the change in position of an object over time in relation to a reference point. It can be described in terms of distance, displacement, speed, velocity, and acceleration.
2. What are the different types of motion?
Ans. The different types of motion include linear motion, circular motion, rotational motion, periodic motion, and oscillatory motion.
3. What is the difference between speed and velocity?
Ans. Speed is a scalar quantity that measures the rate at which an object covers distance, while velocity is a vector quantity that measures the rate and direction of an object's motion.
4. How is acceleration related to motion?
Ans. Acceleration is the rate of change of velocity with respect to time. It can be positive (increasing velocity), negative (decreasing velocity), or zero (constant velocity).
5. How can the motion of an object be represented graphically?
Ans. The motion of an object can be represented graphically using distance-time graphs, speed-time graphs, or velocity-time graphs. These graphs show the relationship between different motion parameters over time.
