Question
If two forces of 5 N and 3 N are acting in the same direction, what is the resultant force? Draw a diagram to illustrate your answer.
Answer
The resultant force is 8 N in the same direction as the two forces. In the diagram, I would draw one arrow of 5 N and another arrow of 3 N, both pointing in the same direction, with a third arrow of 8 N representing the resultant force.
Explanation
This question assesses the student's ability to calculate resultant forces when forces act in the same direction and to represent this visually. It reinforces the concept of vector addition in a practical context.
Common mistake
Misunderstanding Force Arrow Representation
Students often draw force arrows of equal length for forces that are not equal in magnitude.
Ensure that the length of each arrow accurately represents the magnitude of the force; longer arrows indicate greater forces.
