7. General Motion: Terms & Definitions

Question 1

Angular Motion

Answer 1

circular movement around a fixed axis of rotation

Question 2

Centripetal Acceleration

Answer 2

linear acceleration directed towards the axis of rotation

Question 3

General Motion

Answer 3

combination of linear and angular motion

Question 4

Linear Motion

Answer 4

motion alone a stright or curved line, where all point move the same sistance in the same direction at the same time

Question 5

Radian

Answer 5

the ratio between the length of the arc of the circle and the radius of the circle

Question 6

Radius of Rotation

Answer 6

the distance between the axis of rotation and a point of interest

Question 7

Tangent

Answer 7

A tangent is a straight line or segment that touches a curve at a single point without crossing it

Question 8

Tangential Acceleration

Answer 8

linear acceleration in the direction of rotation

Question 9

Tangential Velocity

Answer 9

Tangential velocity is the linear velocity of a point on a rotating object, measured along the tangent to the circular path at that point.

Question 10

Total Acceleration

Answer 10

the square root of the sum of tangential and centripetal acceleration
