Ans: The ends of the long bones are covered by the layer of a hyaline cartilage, they are also known as articular cartilage. These cartilages help in providing a smooth and slippery surface that allows for smooth movement at the joints. They will thus reduce the friction between the bones and therefore absorb shock. It will protect the long bones from wear and tear and will maintain the mobility of the bones.
The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.
Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.

Movement is generally described as a state of changing the position from rest to motion or vice-versa. Movement can be both voluntary movement and involuntary movement. Movement helps an organism perform essential functions, such as pumping blood to the different parts of the body, etc.
