speed and velocity

The measuring unit of acceleration is ..........................

• m/s

• m/s²

• m

• joule

From the vector physical quantities is .....................................

• force

• time

• mass

• distance

The ( distance - time ) graph that represents the body moves with regular speed is represented by a straight line ............................................

• parallel to time axis

• passing by origin point

• perpendicular on time axis

• perpendicular on the distance axis

When a body moves 100 m east and then 50 m east ,so the displacement = ............................ m

• 50 m east

• 150 m east

• 50 m west

• 150 m west

If the distance = 4 t , so the speed = .................... m/s

• 1

• 2

• 3

• 4

A body moves with a speed of 30 m/s for 20 seconds , then it covers 30 m in 1 sec , so its acceleration = ....................... m/s²
