Force definitions
Define force
A push or pull that occurs when two objects interact.
An athlete lands from a jump. Which force is acting?
Ground force reaction
Explain where friction force occurs in physical activity.
Between a shoe and the ground during sprinting or changing direction.
Explain how increasing friction can improve sprint acceleration.
Increasing friction between the shoe and the track allows the athlete to push harder without slipping, improving acceleration.
What the sentence (one word).
Summation of forces occurs when all body parts act together _________.
Sequentially.
Define ground force reaction.
A force exerted by the ground on a body or object that comes into contact with it.
What force occurs at a joint due to bones pressing against each other?
Joint force reaction.
Explain where gravitational force occurs in sport
During a jump, landing, or when a ball travels downward after being thrown.
How can an athlete manage drag force to improve performance?
By reducing drag through body position or equipment, an athlete can move faster and more efficiently.
What happens to performance if force summation is poor?
The movement becomes less efficient, resulting in reduced speed, distance, or force because the body segments are not coordinated effectively.
Define ground force reaction
A force exerted by the ground on a body or object that comes into contact with it
What force occurs when a stretched band recoils
Elastic force.
Explain where elastic force occurs in sport
Elastic force occurs when a springboard is compressed and then recoils, helping the athlete jump higher.
Explain how elastic force can increase power in a movement
Elastic force stores energy when muscles or equipment stretch and releases it to increase power.
1.The number of body parts used in the movement.
2. The order and timing of the sequencing.
3. The force and velocity generated.
4. The way in which the body and each part of the body is stabilised and balanced.
