Physics MCQ Questions class 9 Motion with Answers Important points to remember 

  1. The change of position of object is called as motion. 
  2. It is expressed interms of displacement, velocity, acceleration and time. Simple kinematics is a branch of science which deals with the study of motion of object. 
  3. In motion of magnet, the magmitude and direction of velocity changes with time. The object in such a situation moves on curved path in a plane. This type of motion is called plane motion. 
  4. In projectile motion both magnitude and direction of acceleration remains constarnt, while in circular motion magnitude remains constant but direction changes continuously.
  5.  The motion of object or body or particle along the circumference of a circle is called circular motion.
  6. Examples of circular motion are Motion of satellite around the earth, Motion of electron around the nucleus, Motion of earth around the sun.
  7. Displacement is a shortest path between initial and final position of body whereas distance is a actual length of path travelled by body irrespective of direction.
  8. Motion of a particle along the circumference of a circle with constant angular velocity is called Uniform Circular Motion (U.C.M.) and work done on the body in U.C.M. by centripetal force is zero.
  9. Angular acceleration, angular velocity and angular displacement have same direction, given by right hand rule.
