Question

An object follows curved path. Which of the following quantities may remain constant during the motion

• A. speed
• B. velocity
• C. acceleration
• D. magnitude of acceleration

Answer 1

Answer: (A), (D)

speed
magnitude of acceleration

When an object follows curved path, its magnitude of linear velocity i.e. speed will not change but direction will change continuously. Hence, the acceleration of an object will change but its magnitude will remains constant in any direction.
