Question

Define: a)displacement b)average speed c)average velocity

Answer 1

Answer:

a) the shortest distance travelled by an object is called displacement

b) the average speed of an object, you must know the total distance an object travels and the total elapsed time of its whole journey. The three parts in the triangle are set up in their correct positions mathematically: To get average speed, s , divide total distance by elapsed time: Dt.

c) The average velocity of an object is its total displacement divided by the total time taken. In other words, it is the rate at which an object changes its position from one place to another. Average velocity is a vector quantity. The SI unit is meters per second.
