What is KINEMATICS? 1. What is uniform speed? An object covers the same distance in different intervals of time. An object covers different distances in the same interval of time. An object covers different distances in different intervals of time. An object covers equal distance in equal intervals of time. 2. What is the difference between speed and velocity? Speed is a scalar quantity while velocity is a vector quantity. Speed is the rate of change of velocity while velocity is the rate of change of speed. Speed is a vector quantity while velocity is a scalar quantity. Speed and velocity are the same. 3. What is the formula for velocity? V = d/t D = st V = s/t D = vt 4. What is uniform velocity? A body covers different distances in different intervals of time in a particular direction. A body covers different distances in the same interval of time in a particular direction. A body covers the same distance in different intervals of time in a particular direction. A body covers equal distances in equal intervals of time in a particular direction. 5. What is acceleration? The rate of change of speed with respect to time. The rate of change of velocity with respect to time. The rate of change of displacement with respect to time. The rate of change of distance with respect to time. 6. What is the formula for acceleration? A = v – u/t A = s/t A = d/t A = v/t 7. What is uniform acceleration? A body has a changing rate of change of velocity. A body has a constant rate of change of speed. A body has a constant rate of change of velocity. A body has a changing rate of change of speed. 8. What is distance? The distance measured in a straight line in a particular direction. Total length covered by moving body without mentioning direction of motion. The rate of change of position of an object. The rate of change of velocity of an object with respect to time. 9. What is the SI unit of distance? Minute (min) Meter (m) Kilometer (km) Second (s) 10. What is displacement? The rate of change of velocity of an object with respect to time. The total length covered by a moving body without mentioning direction of motion. The distance measured in a straight line in a particular direction. The rate of change of position of an object. Loading … Pages: 1 2 3 4
