Q

6 factors of sequential summation of force

A
  • The stronger and larger muscles of the thighs and trunk are moved first followed by the smaller and faster muscles.
  • Sequentially accelerate each body part so that optimum momentum passes from one body part to the next.
  • Each body part should be stable so that the next body part accelerates around a stable base to transfer momentum.
  • Use as many body parts as possible, so force can be applied over the maximum possible time.
  • Follow through is important to prevent deceleration of last segment and safe dissipation of force.
  • Ensure all forces are directed towards the target.

Q

Newton’s 2nd Law of motion

A

Acceleration

The acceleration of a body is proportional to the force applied to it and inversely proportional to the mass of the object

  • The greater a force applied to an object, the faster the acceleration
  • if the same force is applied to 2 objects with differing mass, the object with less mass will accelerate faster.

Q

Momentum

A

The measure of the amount of motion possessed by a moving body

Mass x velocity

Momentum is how fast something is travelling multiplied by how heavy something is

(Acceleration but at one speed)

Q

Simultaneous summation

A

All body parts move at the same time to produce a force

Generally to produce accuracy, however some require this method for power

Q

Newton’s 1st law

A

Inertia
A body continues in its state of rest/motion until it is acted upon by a force

The greater an objects inertia, the greater the force required to initiate its movement or change its state of motion.

Q

What’s the conservation of momentum?

A

When collisions occur, an equal and opposite force occurs resulting in a transfer of momentum from one object to the other.

The total momentum of two objects before and after impact are equal. The momentum of one object is transferred to the other on contact, resulting in a transfer of momentum

Q

Sequential summation of force

A

A sequential combination of forces produced by different parts of the body.
Order of segments is a progression from biggest/ strongest to to smallest/ finest

Used to create the largest force/ acceleration possible

Q

The amount of resistance to a change in an objects state of motion.

Eg. Shot put needs a larger force to change its state of motion due to its large mass

Vs

Q

Example of Newton’s 3rd law

A

A standing start has downwards force production, creating an upwards movement. A crouch start maximises force in the opposite direction in which you want to move, therefore having a sideways force production, allowing you to have more force in the direction you would like to go.
