Vertical ground reaction force dey represent external force wey the gymnasts gats overcome with their muscle force and e dey affect the gymnasts linear and angular momentum. Another important thing wey dey affect linear and angular momentum na the time wey the landing take. Gymnasts fit change the shape of the area by increasing the time wey dem take to land. Gymnasts fit achieve dis by increasing hip, knee and ankle amplitude. As the height dey increase, the amplitude for ankles, knees and hips go rise for the bars.```
