Worked Solution & Example Answer:Michéal completes one lap of a running track at a constant speed of 6 m s⁻¹ - Junior Cycle Science - Question (b) - 2017
Step 2
Explain your answer.
Answer
Although Michéal runs at a constant speed of 6 m s⁻¹, velocity is a vector quantity, which means it has both magnitude and direction. At points A and B on the track, Michéal is traveling in different directions even though his speed remains the same. Therefore, the velocities at A and B are different due to the change in direction.
