An interactive test for  Scalar and Vector Physical Quantities . In this lesson  you have learned that: Physical quantity It is any quantity  that can be determined and has a unit of measuring in our life . Notes 1.Each physical quantity is measured in a special measurement unit. 2. Physical quantities are classified into scalars and vectors . Scalar physical quantity It's the physical quantity that has magnitude only and has no direction. Examples Time, energy, temperature, mass, length, speed, radius, area, density. Vector physical quantity It's the physical quantity that has magnitude and direction. Examples displacement ,  acceleration ,  velocity ,  force and weight. Distance It's the actual length of the path that a moving body covers from the starting point to the ending point Displacement It's the length of the shortest straight line between the starting point and the ending point. Description of the quiz: The quiz includes questions fo...

  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...

An interactive test for Prep 3 on Motion in One Direction. In this lesson  you have learned that: Motion It is change of an object's location (position) as time passes according to the location of another object. The simplest type of motion is the motion in a straight line in one direction. (Example: the movement of the train). Speed it is the distance moved through a unit time. ( OR It’s the rate of change of distance) The two factors necessary for the description of movement: 1.  The distance (d) covered by the moving body.     2. The time (t) taken by the moving body to cover this distance. The measuring units of speed are: Meter/second (m/s) Kilometer/hour (km/h) Uniform (regular) speed: It's the speed by which the object covers equal distances at equal periods of time. Non-uniform (irregular) speed: It's the speed by which the object covers unequal distances in equal periods of time OR It's the speed by which the object covers equal distances in unequal ...
