1)random motion and oscillitory Motion.
2)movable joints and immovable joints ​

Answer 1

Answer:

Random motion. Oscillatory motion

For example:. Children playing in a garden For example. : Movement of the pendulum of a clock

Answer 2

Answer:

1)The type of motion in which the direction of motion and the speed of an object changes continuously is called random motion. The type of motion in which the object moves to and fro repeatedly about a mean or a fixed position is known as oscillatory motion.

2)Immovable joints allow no movement because the bones at these joints are held securely together by dense collagen. The bones of the skull are connected by immovable joints.

Partly movable joints allow only very limited movement. Bones at these joints are held in place by cartilage. The ribs and sternum are connected by partly movable joints.

Movable joints allow the most movement. Bones at these joints are connected by ligaments. Movable joints are the most common type of joints in the body, so they are described in more detail next.
