linear and angular movement principles

Question 1

conservation of momentum

Answer 1

the total momentum of an of an object will stay constant unless acted on by an external force

Question 2

conservation of momentum equation

Answer 2

p=mv
momentum (p)= mass (m) x velocity (v)

Question 3

conservation of momentum

Answer 3

the momentum of the player before kicking a ball equals the momentum of the ball after it is kicked. after collision, the player slows to zero and the ball moves off

Question 4

force summation

Answer 4

the sequential and movement of multiple body parts to produce maximum velocity

Question 5

force summation principles

Answer 5

1. Body parts
2. sEquence
3. Stability
4. Timing
5. follow through

Question 6

1. Body parts

Answer 6

use as many body parts as possible

Question 7

2. sEquence

Answer 7

activating larger muscles first enables them to generate a large amount of force that can be passed on to other body parts

Question 8

3. Stability

Answer 8

a stable base must be present for maximum acceleration so momentum can be transferred successfully between body parts

Question 9

4. Timing

Answer 9

transferring momentum from one body part to another when at maximum velocity

Question 10

5. follow through

Answer 10

use a follow through to prevent unnecessary deceleration on body parts

Question 11

angular momentum

Answer 11

the amount of angular motion a body possesses
remains constant
the quantity of rotation of a body around an axis

Question 12

angular momentum formula

Answer 12

angular momentum= moment of inertia x angular velocity

Question 13

moment of inertia

Answer 13

a measure of the resistance of a body to change state when rotating

Question 14

angular velocity

Answer 14

the change in angular displacement over time, which indicates how quickly an object rotates

Question 15

impulse

Answer 15

is equal to the change in momentum of an object
momentum breaker or maker

Question 16

impulse formula

Answer 16

impulse (I)= force (f) x time (t)

Question 17

increasing impulse

Answer 17

• throwing/kicking a ball (more force)
• using a follow through (more time)

Question 18

decreasing impulse

Answer 18

• catching a ball (increase the time in which you apply the force)

Question 19

angluar speed

Answer 19

the change in angular distance over time

Question 20

moment of inertia formula

Answer 20

moment of inertia= mass x radius ^2
MOI = m x r^2

Question 21

momentum

Answer 21

the quantity of motion a body has
the product of a bodys mass and its velocity

Question 22

momentum formula

Answer 22

momentum (p)= mass (m) x velocity (v)
