An interactive test on acceleration and graphic representation of motion
An interactive test for Prep 3 on acceleration and graphic representation of motion. In this lesson you have learned that: 1- The (distance-time) graph for an object moves with a regular speed is represented by a straight line passing through the origin point. 2- The distance (d) is directly proportional to the time. 3. The ratio (d/t ) is a constant value represents the regular speed. 4- The (speed-time) graph for an object moves with regular speed is represented by a straight line parallel to the time axis. Acceleration: It’s the change of an object speed in one second in a specific direction.(OR It’s the rate of change of speed) Notes: 1- When the car's speed increases by time, the movement described as "accelerating motion" or "positive acceleration". (Because the final speed is greater than the initial speed). 2- When the car's speed decreases by time, the movement described as "decelerating motion" or "negative acceleration...
