Summer Holidays Home Work Class IX Subject Physics 1. Differentiate between the following i) Speed and velocity ii) Distance and displacement iii) uniform motion and Non-uniform motion. iv) uniform velocity and variable velocity. 2. Give reasons for the following. i) Can a body move with constant acceleration but with zero velocity? If yes, why? speed ii) Can a body move with constant in an acierated motion? If yes, Give reason. 3. Give answer in detail: i) What do you understand bya) Displacement time graph. b) Velocity time graph. ii) Draw a displacement time graph for a girl going to school with uniform velocity. How can we calculate uniform velocity from it. iii) From a velocity time graph, how can we find a) acceleration of a body b) Displacement of a body 4. Numerical Problemsi) The velocity of a car is 18 m/s, express this velocity in km/h. ii) An electric engine has a velocity of 120 km/h.
