Worked Solution & Example Answer:10 (a) Which row of the table is correct for both force and velocity? A B C D (b) Figure 20 shows a satellite orbiting the Earth - Edexcel - GCSE Physics - Question 10 - 2018 - Paper 1
Step 1
Which row of the table is correct for both force and velocity?
Answer
The correct row is B: 'scalar' for force and 'vector' for velocity. Force is a vector quantity as it has both magnitude and direction, while velocity is also a vector quantity representing the rate of change of displacement.
Step 2
Step 3
Draw an arrow on Figure 20 to show the direction of the force acting on the satellite, that keeps it in orbit around the Earth.
Answer
An arrow should be drawn pointing from the satellite towards the center of the Earth, indicating the direction of the gravitational force acting on the satellite. This arrow can be labeled 'F'.
