Questions & Step-by-Step Solutions
If a force of 5 N acts on an object and moves it 4 m in the direction of the force, what is the work done?
Correct Answer: 20 J
Step 1: Identify the force acting on the object. In this case, the force is 5 N (Newtons).
Step 2: Identify the distance the object moves in the direction of the force. Here, the distance is 4 m (meters).
Step 3: Use the formula for work done, which is Work = Force × Distance.
Step 4: Substitute the values into the formula: Work = 5 N × 4 m.
Step 5: Calculate the result: 5 N × 4 m = 20 J (Joules).
Step 6: Conclude that the work done is 20 J.
Work – Work is defined as the product of the force applied to an object and the distance over which that force is applied in the direction of the force.
Units of Work – Work is measured in joules (J), where 1 joule is equivalent to 1 newton meter (1 J = 1 N·m).
