Physics Experiment Quiz

What does the experiment with the wheel sensor demonstrate about velocity?

• Velocity remains constant over time.

• Velocity fluctuates randomly over time.

• Velocity increases linearly with time.

• Velocity decreases linearly with time.

In the rotational kinematics experiment, what is used to calculate the moment of inertia?

• The color of the masking tape.

• The kinetic energy and MGH.

• The mass of the masking tape rolls.

• The height of the ramp.

What is the role of the gyroscope in the torque experiment?

• To measure the color of the object.

• To measure the rotation rate.

• To measure the mass of the object.

• To measure the temperature.

How do students determine the force exerted by the felt pads in the torque experiment?

• By observing the color change of the pads.

• By weighing the pads.

• By calculating the coefficient of friction and lever arm.

• By measuring the temperature of the pads.

What is the significance of a constant rate of change of angular velocity in the z direction?

• It suggests a constant angular acceleration.

• It indicates a variable torque.

• It shows a decreasing angular acceleration.

• It implies no angular acceleration.
