ROTATIONAL MOTION

What is the primary reason the vector product is called a 'cross product'?

• Because it crosses two vectors
• Because it results in a crossing path
• Because it uses the '×' symbol in notation
• Because it forms a cross shape

What is the vector product of position and linear momentum?

• Force
• Torque
• Angular momentum
• Energy

What is the result of j × k?

• −i
• i
• j
• k

If a × b = 0, which of the following must be true?

• They are perpendicular
• They are equal
• Either a or b is zero, or they are parallel
• One is a scalar

What happens to the cross product if one vector is doubled?

• Magnitude unchanged
• Magnitude doubles, direction unchanged
• Becomes zero
• Reverses direction
