SCALARS and VECTORS - Distance, Displacement, Speed, Velocity

John walked from his home to the park and then to the grocery store. What is the difference between the total distance he walked and his displacement?

• Distance is the longest distance John walked from home to the park and then to the grocery store, while displacement is the shortest distance from his home to the grocery store.

• Distance is measured in meters, while displacement is measured in kilometers.

• Distance is the total length of the path John traveled from home to the park and then to the grocery store, while displacement is the shortest distance between his initial position (home) and final position (grocery store).

John is studying physics and he came across different quantities. He is confused about which of the following is a vector quantity. Can you help him?

• mass of an apple

• speed of a running car

• temperature of a cup of coffee

• velocity of a flying bird
