• Reference point

The shortest path from start to end point is known as displacement. In which of the following motion do we usually make use of displacement?

• Acceleration

• Velocity

• Speed

• Distance 

The football player was running 10 miles an hour towards the end zone. Which of the following choices below best describes the mentioned statement?

• It is scalar because it has magnitude. 

• It is vector because it has magnitude and direction.

• It is scalar because it has magnitude and direction.

• It is vector because it has magnitude.

Which of the following statements about displacement and distance is correct?

• Displacement can never be equal to distance.

• Displacement always follows a straight line while distance does not.

• Displacement can either be greater or shorter than the distance taken from point of origin to the destination.

• Displacement measures the length of the straight line from point of origin to its point of destination while distance is the length of path traveled.
