Final answer:

The amount of work done by a 3N force moving an object 1.5M is 4.5 joules. This calculation assumes the force is applied in the same direction as the movement of the object.

Step-by-step explanation:

The concept of work is a key topic in physics, directly relating force and motion applied over a distance. To calculate the work done by a force when an object moves, you use the formula:

Work (W) = Force (F) × Distance (d) × cos(θ)

where θ is the angle between the force vector and the direction of movement. For a constant force that acts along the same line as the movement, the angle θ is 0 degrees, and cos(0) is 1, simplifying the work formula to:

W = F × d

In this case, with a force of 3N moving an object 1.5M, the angle between the force direction and the movement is 0 (since they are in the same direction), and hence:

W = 3N × 1.5M = 4.5 joules of work done

One joule (J) is defined as the amount of work done when a force of 1 newton displaces an object by 1 meter in the direction of the force. Hence, applying a force of 3N over a distance of 1.5M results in 4.5 J of work being performed, according to the example provided.
