A javelin thrown by an athlete is in ________ motion.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. curvilinear.
A javelin thrown by an athlete is in curvilinear motion. This type of motion occurs when an object follows a curved path, which is typical for projectiles like a javelin. The trajectory of the javelin is influenced by both its initial velocity and the forces acting on it, such as gravity and air resistance. While the motion may seem periodic (repeating certain characteristics), it primarily follows a curved path, classifying it as a curvilinear motion.
