Worked Solution & Example Answer:A man pulls a suitcase with a horizontal force, F, as shown in Figure 5 - Edexcel - GCSE Physics Combined Science - Question 4 - 2016 - Paper 1
Step 1
Which of these gives the correct names for the forces P and Q?
Answer
To identify the forces acting on the suitcase in Figure 5, we need to understand the context of the situation.
Force P is directed upwards, likely counteracting the weight of the suitcase, which indicates that it is a supporting force typically referred to as a reaction force. Thus, we can categorize force P as a 'reaction'.
Force Q, on the other hand, is directed against the motion of the suitcase. This suggests that it is resisting the forward motion, typically considered as 'friction'.
Therefore, the correct names for the forces are:
- Force P: Reaction
- Force Q: Friction
This corresponds to answer choice B (reaction for P and friction for Q).
