ROTATIONAL MOTION

What is the vector product used to define in rotational motion?

• Linear velocity and acceleration
• Torque and angular momentum
• Mass and inertia
• Force and displacement

Which rule is illustrated in Fig. 6.15b in the text?

• Screw rule
• Left hand rule
• Right hand rule
• Palm rule

What happens to the cross product if both vectors are reversed?

• It reverses
• It becomes zero
• It doubles
• It remains the same

What is the direction of the screw's tip when rotated from a to b?

• Opposite to a
• Direction of b
• Direction of a × b
• Perpendicular to a only

If a × b = 0 and neither vector is zero, what can be concluded?

• They are perpendicular
• They are equal
• The vectors are parallel
• One is a unit vector
