Types of Motion

Question 1

Angular Motion Definition

Answer 1

Movement around a fixed point or axis, occurs when a force is applied outside the center of mass

Question 2

What Force is applied in Angular Motion

Answer 2

Eccentric Force or Torque (outside force)

Question 3

Torque Definition

Answer 3

Rotational Force applied for an object to turn about its axis of rotation

Question 4

Three Axes of Rotation

Answer 4

Longitudinal, Frontal, Transverse

Question 5

Angular Motion Key Descriptors

Answer 5

Angular Velocity, Displacement, Moment of Inertia, Angular Momentum

Question 6

Angular Velocity

Answer 6

• Vector Quantity (reference to direction)
• Displacement of an object on a pivot or axis in an angular motion in relation to time
• Ex. Bike Tire, Figure skater Spin

Question 7

Inertia

Answer 7

• Resistance to change of a body to angular motion
• 2 main factors, Mass and Distribution of Mass
• Greater Mass= greater inertia (resistance to change)
• Closer Mass to the axis=less inertia (less resistance) vice versa

Question 8

Angular momentum (spin)

Answer 8

• Object or boyd move around an axis or point of rotation

- Impacted by angular velocity and moment of inertia
