Why is a larger area of contact beneficial for force absorption?

It spreads the force over a wider area, reducing injury

Answers

1
Why is a larger area of contact beneficial for force absorption?
It increases the impact on a specific body part
It focuses the force into one area
It spreads the force over a wider area, reducing injury
It makes the landing faster
2
Which of the following best explains how the body absorbs force when landing from a jump?
Keeping legs straight to reduce contact time
Bending knees, hips, and ankles to increase movement length
Locking knees to brace impact
Landing on toes only
3
Ways to absorb force include increasing the movement length, increasing the time of absorption and increasing the area
False
True
4
Which of the following is an example of a non-contact external force?
Friction
Ground Reaction Force
Air Resistance
Gravity
5
What type of force is applied when a soccer player kicks a ball?
Air resistance
External contact force
Internal force only
Non-contact force
6
What is the main purpose of increasing time during force absorption (e.g. catching a ball softly)?
To apply more power
To reduce the peak force
To speed up the motion
To change direction quickly
7
What is the formula used to calculate force?
F = M ÷ A
F = A - M
F = M x A
F = M + A
8
Which of the following is an example of internal force?
Air resistance
Muscle contraction
Friction
Gravity
9
Which statement best describes sequential summation of force?
Fewer segments are used to increase accuracy
Body segments are not involved in force production
All body segments move at once for power
One body segment moves after another to generate power
10
Both the body and sports equipment can apply force during sport
True
False
