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"
(Because the final speed is less than the initial speed).

3- When the body moves with regular speed, its acceleration is zero.

Measuring units of acceleration

m/s² or km/h²

Uniform acceleration

It's the acceleration by which the object moves in a straight line when its speed changes by equal values through equal periods of time
