This means that any change in vertical speed is due to gravitational acceleration, which is 9. 65 m and acceleration of 3. Assemblies. For example, an object moving in a circle at constant speed is NOT moving at constant velocity, because the direction of its motion is constantly changing. The average velocity during the 1-h interval from 40 km/h to 80 km/h is 60 km/h: v – = v 0 + v 2 = 40 km/h + 80 km/h 2 = 60 km/h. 75 m /s ]Acceleration is a change in the speed of an object (contrary to popular belief - acceleration ban be an increase or decrease in speed). Hope it will help you. Moving objects are having static or varying velocity.
