Kinematics Key Concepts

Question 1

Linear motion

Answer 1

Motion that occurs in either a straight line or curved path.

Question 2

Angular motion

Answer 2

Takes place when a body moves along a circular path around an axis.

Question 3

Distance

Answer 3

How much ground an object covers throughout its motion.

Question 4

Displacement

Answer 4

The difference between the initial position and the final position of an object with reference to direction.

Question 5

Speed

Answer 5

The rate (how fast) a person/object is covering distance.

Question 6

Velocity

Answer 6

How fast the person/object covers distance and what direction they have moved.

Question 7

Acceleration

Answer 7

The rate the person/object is changing velocity.

Question 8

Why learn biomechanics? (3 reasons)

Answer 8

-Describe and explain movement
-Determine optimal techniques to improve performance
-Helps to avoid injury

Question 9

General motion

Answer 9

-Movement involves both linear and angular motion.
-Most human movement is GENERAL because we use joints to create force for motion.
