Solution
The correct options are
A Speed
C Acceleration
D Magnitude of acceleration
Speed can remain constant eg. uniform circular motion.
acceleration can remain constant eg. projectile. In projectile acceleration is always acceleration due to gravity (g).
but when a particle is in a curved path, direction of motion is continuously changing. Hence velocity also keep changing. So the correct options are 'A' 'C' and 'D'.
