Question 1

Two points are located on a rigid body that rotates through 56°. Point A is 0.67 m from the axis of rotation and point B is 0.65m from the axis of rotation - which point moves the furthest linear distance?

Accepted Answer

The point that is furthest away from the axis of rotation will move the greatest linear distance i.e. point A is 0.67m away

Question 2

There is no relationship between linear and angular motion and they work independently of each other

Accepted Answer

There are several mathematical relationships between linear and angualr motion

Question 3

Angular Velocity is defined as Angular Acceleration divided by Time

Accepted Answer

Angular Velocity is Angular Displacement/time

Question 4

Angular distance is the arc length of the curve created by angular motion of a rigid body

Accepted Answer

This is how angular distance is determined by calculating the arc length using s = rθ

Question 5

A point that is closer to the axis of rotation of a rigid body will move a shorter linear distance than a point that is further away from the axis of rotation

Accepted Answer

The linear distance (arc length) moved by the point that is further away from the axis of rotation will move the greatest linear distance

Question 6

It is possible to have an angular orientation of a point

Accepted Answer

Technically a point cannot have an angular orientation or movement

Question 7

A tangent is defined as a line that touches a curve at a point and the line will have the same gradient (slope of a line measured as its ratio of vertical to horizontal change) as that of the curve at that point.

Accepted Answer

This is the correct definition of a tangent in this context

Question 8

Three points are located on a rigid body that moves through 87° in 2.45s. Point A is 0.76m; point B is 0.86m and point C is 0.96m from the axis of rotation respectively. Determine the linear distance moved by each point?
