Question

Calculate the final displacement from 0 if an object first moves 3 cm to the left and then 5 cm to the right.

Calculate the final displacement from 0 if an object first moves 3 cm to the left and then 5 cm to the right.
The final displacement is [1-5] cm to the [right or left ].

Answer 1

Answer: 2 cm to the right

Explanation:

The displacement is the shortest distance between initial and final position.

It can be calculated by subtracting the initial position from final position.

Let the sign be positive for direction towards right and negative for direction towards left.

The initial position is 0.

Firstly, object moves towards left = -3 cm

Then, the object moves towards right = 5 cm

Thus, the final position of the object is = -3 cm + 5 cm = +2 cm

Displacement = final position - initial position = + 2 cm - 0 = + 2 cm

Thus, the final displacement is 2 cm to right.

Answer 2

We have that the Displacement is mathematically given as

Displacement =2cm

From the question we are told

Calculate the final displacement from 0 if an object first moves 3 cm to the left and then 5 cm to the right.
