acceleration test

write your name

when the final speed greater than initial speed means that the body moves with

• accelerating motion
• decelerating motion

............................is the rate of change of speed

• distance
• speed
• acceleration

the acceleration in the period BC is

• positive
• negative
• zero

...................... is the measuring unit of acceleration

• m
• m/s2
• m/s

when the final speed is less than initial speed we can say that the body moves with ................. acceleration

• zero
• positive
• negative

when the speed changes by equal values at equal periods of time we can say that the body moves with .......................

• uniform speed
• uniform acceleration
• non uniform acceleration

acceleration is the result of multiplying the speed of a moving object by time

• right
• wrong

speedometer is used to measure the ..................of the car

• speed
• distance
• acceleration

if the speed decreases 5 m/sec. every one sec. the value of acceleration

• 5 m/s2
• zero
• -5m/s2
