TRANSCRIPT

1. Welcome 2. Presented byAKHILA.K.RAJCANDIDATE CODE: 18213361003PHYSICAL SCIENCE 3. MOTION 4. FRAME OF REFERENCE The background or point that is usedfor comparison when motion isdescribed. The most common frame of referenceis the Earth. 5. Motion is the change in position relativeto the frame of reference in a certainamount of time. 6. Speed is the rate at which an object moves. Speed= 7. 80 km/hr 8. Velocity is speed in a given direction. 9. What is acceleration?What is the formula foracceleration? The rate of change in velocity is known asacceleration. Acceleration =final velocity original velocitytime 10. 18,000 Kilometers/hour 11. The velocity is continuously changingbecause direction is continuously changing. An object in circular motion is acceleratingeven though its speed may be constant. 12. Momentum is equal to the mass of an objectmultiplied by its velocity Momentum= Mass X Velocity 13. How is momentum conserved? The total momentum of any group of objectremains the same unless outside influencesact on the objects. 14. THANK YOU
