What is Work?

In physics, work is defined as the energy transferred to or from an object when a force is applied over a displacement. It quantifies how much energy is used to move an object or change its motion.

  • Force (F): The constant force applied to the object.
  • Displacement (d): The distance over which the force is applied.
  • Angle (θ): The angle between the direction of the force and the direction of displacement.

Calculation Formula

The total work done \(W\) when a constant force is applied is given by the formula:

$$W = F \times d \times \cos(\theta)$$

Where:

  • \(W\): Work done, typically measured in Joules (J).
  • \(F\): Force applied, measured in Newtons (N).
  • \(d\): Displacement, measured in meters (m).
  • \(\theta\): The angle between the force vector and the displacement vector.

Key Concepts

  • Force: The push or pull acting upon an object.
  • Displacement: The change in position of an object.
  • Cosine of the Angle: Adjusts the work calculation to account for the direction of the force relative to the displacement.
  • Energy Transfer: Work is a measure of the energy transferred to or from an object.

Step-by-Step Calculation Process

  1. Identify the Parameters:

    Determine the constant force \(F\), the displacement \(d\), and the angle \(\theta\) between the force and displacement.

  2. Apply the Formula:

    Substitute your values into the work formula:

    $$W = F \times d \times \cos(\theta)$$

  3. Compute the Cosine:

    Calculate the cosine of the angle \(\theta\) to account for the direction of the force.

  4. Calculate the Work:

    Multiply the force, displacement, and the cosine of the angle to determine the total work done.

  5. Review the Result:

    Verify the units and ensure the calculated work aligns with the expected energy transfer.

Practical Examples

Example: Calculating Work Done with a Horizontal Force

Scenario: A force of 20 N is applied horizontally to push a box over a distance of 5 m. Since the force is applied in the direction of motion, the angle \(\theta\) is 0°.

  1. Parameters: \(F = 20 \, \text{N}\), \(d = 5 \, \text{m}\), \(\theta = 0°\).
  2. Compute Cosine: \(\cos(0°) = 1\).
  3. Apply the Formula:

    $$W = 20 \times 5 \times 1 = 100 \, \text{J}$$

  4. Result: The total work done is 100 Joules.
