Which of the following is accelerating?
An object moving with a constant velocity.
An object moving along a curve.
An object moving on a straught line with a constant speed.
An object moving along a curve experiences centripetal acceleration.
we know that velocity is either change with magnitude or direction also.
and Acceleration is rate of change of velocity.
SO when object move along a curve or circular path, object having same magnitude but change the direction continuosly so it is accelerating.
When object move along straight path object has same direction and may depend only magnitude.
