Unformatted text preview: Acceleration = final velocity original velocity time A car is traveling at 60 km/hr. It accelerates to 85 km/hr in 5 seconds. What is the acceleration of the car? 18,000 kilometers/hour Circular Motion The velocity is continuously changing because direction is continuously changing. An object in circular motion is accelerating even though its speed may be constant. What is momentum? Momentum is equal to the mass of an object multiplied by its velocity Momentum = Mass x Velocity How is momentum conserved? The total momentum of any group of objects remains the same unless outside influences act on the objects. GOOD LUCK ON YOUR TEST! Make sure and study!...
