Which of the following four ‘motions' is different from the other three?​

Answer 1

Answer:

ANSWER

Curvilinear motion is defined as a motion that occurs when a particle travels along a curved path. The curved path can be in two dimensions (in a plane), or in three dimensions.

Apple will fall in a straight line so this motion is rectilinear motion.

the spinning wheel is a circular motion

pendulum will perform SHM

Javelin is thrown at some angle with horizontal so will have an acceleration at some angle with the velocity so the path followed will be curved. So-called curvilinear motion.
