Science Slope of the velocity - time graph gives speed displacement distance acceleration Unit of acceleration is ms-1 ms-2 ms ms2 The force responsible for drying of clothes in a washing machine is Centripetal force Centrifugal force Gravitational force Electrostatic force In a 100 m race, the winner takes 10 s to reach the finishing point. The average speed of the winner is ___________ ms-1. 5 10 20 40 Speed is never ______ fraction negative zero positive Speed is a ____________ quantity whereas velocity is a ____________ quantity Consider an object is rest at position x = 20m. Then its displacement – time graph will be straight line to _____________ the axis. Area under velocity ‒ time graph shows ____________ The graph of uniform motion is _____ Acceleration is a _____ quantity. The motion of a city bus in a heavy traffic road is an example for uniform motion Distance covered by a particle never becomes zero but displacement becomes zero If the velocity – time graph of a particle is a straight line inclined to X-axis then its displacement – time graph will be a straight line? For a freely falling body the acceleration 'a' is replaced by s. Giant wheel moves a vertical linear path. Motion of a body covering equal distances in equal interval of time m/s Constant retardation Uniform acceleration m Speed Distance Define distance. What is speed? What is acceleration? A student takes 15 minutes to travel from his home to school with a uniform speed of 5km/h. What is the distance of his school from the home? An object travels 16m in 4s and then another 16m in 2s. What is the average speed of the object? Define velocity? Distinguish distance and displacement. Derive equations of motion by graphical method. A racing car has a uniform acceleration of 4 ms-2. What distance it covers in 10 s after start?
