Linear Kinematics 2

Question 1

Displacement equation

Answer 1

Final position-initial position

Question 2

Answer 2

(Final position-initial position)/time

Question 3

Acceleration equation

Answer 3

(Final velocity-initial velocity)/time

Question 4

What is the initial and final position of a bicep curl in the horizontal plane of the UP phase

Answer 4

Initial- 0.5
Final- 0.6

Question 5

What is the initial and final position of a bicep curl in the vertical plane of the UP phase

Answer 5

Initial- 0.25
Final- 0.75

Question 6

How do the up and down phases of a bicep curl change?

Answer 6

Initial and final positions are just reversed (change signs)

Question 7

What is the shape of the horizontal position graph during the up phase of a bicep curl

Answer 7

Hill and valley

Question 8

What is the shape of the vertical position graph during the up phase of a bicep curl

Answer 8

Hill

Question 9

For linear velocity what does the sign tell you?

Answer 9

Direction of travel

Question 10

Position to velocity is known as what in calc

Answer 10

Derivative (velocity is the slope of position)

Question 11

Velocity to position is known as what in calc

Answer 11

Integration (area under the curve)

Question 12

How is instantaneous velocity acheived

Answer 12

As the change in time approaches 0 for displacement
