11.1 Linear Motion

Which of the following defines distance?

• The shortest path from a starting point to an ending point.

• The rate of change of position in a specific direction.

• The total path traveled by an object.

• The rate of change of speed over time.

An object travels in a straight line for 50 m and then turns around and travels back 20 m. What is the total distance traveled by the object?

• 30 m

• 50 m

• 70 m

• 20 m

The formula for calculating speed is:

• Speed=Distance/Time​

• Speed=Time/Distance​

• Speed=Distance X Time

• Speed=Time−Distance

A car travels 180 km in 3 hours. What is its average speed?

• 50 km/h

• 60 km/h

• 60 m/s

• 183 km/h

A bus is moving at a constant speed in a straight line. Which of the following statements is true about its motion?

• It has non-uniform velocity.

• It has non-uniform speed.

• It has uniform velocity.

• It is accelerating.

A car increases its speed from 10 m/s to 22 m/s in 6 s along a straight road. What is the acceleration?

• 1 m/s²

• 2 m/s²

• 3 m/s²

• 4 m/s²

A car travels 120 m east in 20 s. What is the velocity of the car?

• 5 m/s east

• 5 m/s west

• 6 m/s east

• 6 m/s west

A cyclist starts from rest and increases speed steadily along a straight track. This motion is an example of:

• Uniform motion

• Accelerated motion

• Decelerated motion

• Non-uniform but constant speed
