Rotational Motion Quiz

What is the difference between linear motion and rotational motion?

• Linear motion and rotational motion are the same

• Linear motion is in a straight line, while rotational motion involves spinning or rotating

• Linear motion is in a circle, while rotational motion is in a straight line

• Linear motion involves spinning or rotating, while rotational motion is in a straight line

What is the unit for angular displacement?

• Hertz

• Degrees per second

• Radians per second

• Meters per second

What is the equation that connects linear velocity to angular velocity?

• v = omega + r

• v = omega - r

• v = omega * r

• v = omega / r

What is the unit for frequency?

• Seconds per cycle

• Meters per second squared

• Hertz

• Radians per second squared

What is the equation to calculate angular velocity if you know the frequency?

• omega = 2 * pi * f

• omega = f / 2 * pi

• omega = 2 * pi / f

• omega = pi * f

What is the unit for angular acceleration?

• Hertz

• Seconds per cycle

• Radians per second squared

• Meters per second squared

What is the centripetal acceleration for an object moving with constant speed around a circle?

• omega / r

• omega - r

• omega * r

• omega + r

What is the net acceleration of an object when it's not moving with constant speed around a circle?

• Centripetal acceleration

• Radial acceleration

• Vector sum of centripetal and tangential acceleration

• Tangential acceleration
