Quiz on Angular Motion and Torque

What is angular motion?

• Movement in a straight line

• Movement in a zigzag pattern

• Movement in a circular path around a fixed point

• Random movement

What causes angular motion?

• A force through the centre of mass

• An eccentric force

• Gravity

• Friction

What is the turning force that causes rotation called?

• Momentum

• Inertia

• Torque

• Acceleration

Which statement about torque is correct?

• Torque decreases with distance from the axis.

• Torque is unaffected by the distance from the axis.

• Torque increases with the distance from the axis.

• Torque is only present when the axis moves.

If you apply the same force closer to the axis, what happens?

• Rotation becomes easier.

• Rotation becomes harder.

• Rotation speed increases.

• Rotation stops completely.

What is the formula for torque?

• Torque (Nm) = Distance (m) ÷ Force (N)

• Torque (Nm) = Force (N) × Distance (m)

• Torque (Nm) = Force (N) ÷ Distance (m)

• Torque (Nm) = Distance (m) × Speed (m/s)

According to Newton’s First Law, what happens to a rotating body if no force acts on it?

• It slows down.

• It continues rotating at the same speed.

• It stops immediately.

• It rotates faster.

What does Newton’s Second Law state about angular motion?

• No force is needed to start rotation.

• The greater the torque, the faster the rotation.

• All rotations eventually stop.

• Opposing forces prevent torque.

In Newton’s Third Law, when a diver pushes down on the board, what happens?

• The board doesn’t respond.

• The board pushes the diver up, causing rotation.

• The board absorbs the force.

• The diver stays stationary.

What is angular displacement?

• The speed of rotation.

• The rate of acceleration.

• The smallest angle change between start and end of rotation.

• The total distance travelled in a circle.
