Worked Solution & Example Answer:The diagram shows the forces acting on a car which is travelling along a flat straight road - Edexcel - GCSE Physics - Question 1 - 2013 - Paper 1
Step 1
The size of the resultant force on the car is 350 N. In which direction is the resultant force acting?
Answer
To find the direction of the resultant force, we need to consider the driving force and the drag force acting on the car. The driving force is 800 N to the left, and the drag force is 450 N to the right.
To calculate the resultant force, we subtract the drag force from the driving force:
Thus, the resultant force is acting to the left. The correct answer is: B to the left.
Step 2
Complete the sentence by putting a cross (✓) in the box next to your answer. The car is
Answer
Since there is a resultant force acting on the car (350 N to the left), according to Newton's second law of motion, the car must be accelerating. Therefore, the correct answer is: A accelerating.
