ROTATIONAL MOTION

What is the linear velocity of a particle in rotational motion related to?

• Only angular velocity
• Only radius
• Angular velocity and position vector
• Mass and angular acceleration

What is the primary purpose of using the determinant form for the cross product?

• To make it look complicated
• To provide an easy-to-remember method for computation
• To eliminate the need for unit vectors
• To convert vectors into scalars

In the determinant form of the cross product, what do the rows represent?

• All rows are unit vectors
• All rows are vector components
• First row: unit vectors; second and third: vector components
• Rows are scalars only

What is the sign of the vector product if the unit vectors do not appear in cyclic order?

• Positive
• Negative
• Zero
• Infinite

What happens to the vector product when the unit vectors appear in cyclic order?

• The product is negative
• The product is zero
• The product is positive
• The product is undefined
