biomechanics

Question 1

force

Answer 1

force is any interactions (push or pull).

Question 2

what is forced used for

Answer 2

• get objects moving
• stop objects moving
• change direction
• change speed
• balance

Question 3

what are the three main forces

Answer 3

moving
stopping
balancing

Question 4

external forces

Answer 4

external forces are interactions between the body and the environment. For example gravity, friction, air resistance and water resistance.

Question 5

internal forces

Answer 5

structures of the body that interact to produce movement. muscles and tendons act together to produce forces that causes movement.

Question 6

contact (types of external forces)

Answer 6

contact- forces that act on objects coming into direct forces with one another
example- friction forces. ground reaction forces, wr, ar

Question 7

non contact (types of external forces)

Answer 7

non contact- forces that act on objects without coming into direct contact with on another.. Example- gravity

Question 8

force by the body and equipment

Answer 8

• body is used as a vehicle for applying force

example- moving your leg to kick the soccer ball

Question 9

simultaneously

Answer 9

all the body parts move at the same time to produce force, used to produce accuracy or to attain maximum power for example a putt in gold.

Question 10

sequentially

Answer 10

combination of forces produced by different parts of the body acting together to maximize force for example throwing, kicking and striking.

Question 11

application of force by the body and equipment

Answer 11

“for ever reaction there is an equal and opposite reaction

for example bumper cars, when you hit each other you rebound off.

Question 12

ground reaction forces

Answer 12

Analyzing movement

the force exerted by the ground on a body in contact with it.
