ROTATIONAL MOTION Quiz

• It increases speed
• It does no work
• It does negative work and reduces kinetic energy
• It changes the axis

• It violates conservation
• It makes energy infinite
• It allows calculation of kinetic energy change from torque and angle
• It eliminates mass

• When force is radial
• When force is small
• When it produces maximum torque
• When time is short

• It is the direction of force
• It lies in the plane
• It is the fixed axis of rotation perpendicular to the plane of motion
• It is arbitrary

• It calculates linear force
• It gives scalar work
• It ensures only the perpendicular component of force contributes to torque
• It measures energy
