biomechanical principles

Question 1

newton’s 1st law

Answer 1

• inertia
• a body will remain stationary or move at a constant velocity unless acted upon by a resultant force
• if an object is at rest, it stays at rest
• if it is moving in one direction it will keep moving in that direction until another force is applied to change it

Question 2

in newtons 1st law what will a larger mass create…

Answer 2

a larger mass creates a larger force at the point of inertia

Question 3

intertia

Answer 3

the tendency of an object to resist a change in motion

Question 4

gymnastic example of newtons 1st law

Answer 4

• when running towards a vault (internal force from the muscles) you are moving at a constant pace in the same direction
• until the force applied changes when you hit the vault
• it causes your body and motion to change position.

Question 5

2nd law

Answer 5

law of acceleration- the magnitude of the force governs the acceleration, F= ma.

Question 6

3rd law

Answer 6

law of reaction- For every action force there is an equal and opposite reaction force
