Question: If a force of 10 N is applied to an object and it moves 3 m in the direction of the force, what is the work done? (2021)

Options:

Correct Answer: 30 J

Exam Year: 2021

Solution:

Work done W = F * d = 10 N * 3 m = 30 J.

If a force of 10 N is applied to an object and it moves 3 m in the direction of the force, what is the work done? (2021)

If a force of 10 N is applied to an object and it moves 3 m in the direction of the force, what is the work done? (2021)

Step 1: Identify the force applied to the object. In this case, the force is 10 N (Newtons).
Step 2: Identify the distance the object moves in the direction of the force. Here, the distance is 3 m (meters).
Step 3: Use the formula for work done, which is Work (W) = Force (F) * Distance (d).
Step 4: Substitute the values into the formula: W = 10 N * 3 m.
Step 5: Calculate the result: 10 N * 3 m = 30 J (Joules).
Step 6: Conclude that the work done is 30 J.

Work – Work is defined as the product of the force applied to an object and the distance the object moves in the direction of the force.
Units of Work – Work is measured in joules (J), where 1 joule is equivalent to 1 newton-meter.
