Question

Suppose our school is $1\text{km}$ away from our house, and we go to school in the morning, and in the afternoon we come back. Then, the total displacement for the entire trip is

• A. $1\text{km}$
• B. $2\text{km}$
• C. $-1\text{km}$
• D. $0\text{km}$

Answer 1

The correct option is D $0\text{km}$

The displacement is zero because initial and final positions are same,i.e. home and hence displacement is $0$.
