Speed and velocity

Question 1

what is speed

Answer 1

speed measures how fast an object is traveling

Question 2

how is an average speed of an object defined

Answer 2

the average speed of an object is defined as the distance travelled per unit of time

Question 3

is speed a scalar or vector quantity and why

Answer 3

speed is a scalar quantity because it has magnitude, but not direction

Question 4

how do you calculate average speed

Answer 4

average speed can be calculated by dividing the total distance travelled by the time taken
Speed𝑎𝑣 (average speed) = 𝑑𝑖𝑠𝑡𝑎𝑛𝑐𝑒/𝑡

Question 5

what is velocity

Answer 5

velocity is speed in a given direction

Question 6

is velocity a vector or scalar quantity and why

Answer 6

it is a vector quantity as it has both magnitude and direction

Question 7

how do you calculate average velocity

Answer 7

average velocity can be calculated by dividing displacement over time
V𝑎𝑣= 𝑠/𝑡
