#1
Which of the following is an example of motion?
A flying bird
ExplanationMotion refers to a change in position over time.
#2
What is the formula for calculating speed?
Speed = Distance / Time
ExplanationSpeed is the rate at which an object covers distance.
#3
What is the SI unit of speed?
Meters per second (m/s)
ExplanationSI unit for measuring speed.
#4
A car travels 200 kilometers in 4 hours. What is its speed?
50 km/h
ExplanationSpeed calculation using distance and time.
#5
What is the difference between speed and velocity?
Speed is a scalar quantity, while velocity is a vector quantity.
ExplanationSpeed only indicates magnitude while velocity includes direction.
#6
A train travels 300 meters in 20 seconds. What is its speed?
15 m/s
ExplanationCalculating speed using distance and time.
#7
Which of the following is a correct unit for acceleration?
meters per second squared (m/s²)
ExplanationSI unit for measuring acceleration.
#8
Which of the following is true about velocity?
Velocity is the rate of change of position
ExplanationVelocity includes both speed and direction.
#9
What does a negative acceleration indicate?
The object is slowing down
ExplanationNegative acceleration implies a decrease in speed.
#10
A car accelerates from rest to 30 m/s in 5 seconds. What is its acceleration?
10 m/s²
ExplanationCalculating acceleration using change in speed and time.
#11
Which of the following is a correct unit for velocity?
Meters per second (m/s)
ExplanationStandard unit for expressing velocity.
#12
What is the acceleration of an object moving at a constant speed?
Zero
ExplanationNo change in speed means no acceleration.
