Final answer:
Flexibility, balance, agility, and force are considered gross motor skills, involving large muscle groups and are crucial for coordination and physical activities.
Step-by-step explanation:
Flexibility (toe touching), balance (one leg hop-cerebellum development), agility (juking), and force (general muscle strength) are examples of gross motor skills. These skills involve larger movement patterns requiring the use of big muscle groups. For instance, flexibility such as the ability to touch one's toes, involves the muscles of the back and hamstrings.
Balance, such as performing a one-leg hop, is critically dependent on the cerebellum, which helps develop control and stability. Agility, as demonstrated through juking motions, requires quick changes in direction and speed, which rely on a combination of balance, coordination, and explosive power.
Gross motor skills are crucial in everyday tasks, sports, and various physical activities. They differ from fine motor skills, which require smaller, more precise movements, such as cutting paper shapes with scissors. The development and refinement of gross motor skills are essential for physical fitness, coordination, and the ability to perform complex movements.
