• force, weight and speed

• acceleration, mass and altitude

• force, acceleration and mass

• mass, energy and force

Leaning against a wall and the wall pushing back to support you is an example of ____________________________.

• Newton's 1st law of motion

• Newton's 2nd law of motion

• Newton's 3rd law of motion

• Newton's 4th law of motion

Which of the following is true about weight?

• Weight must be equal and opposite to thrust for the drone to move in the desired direction.

• Weight is related to mass and acts through the center of gravity of the drone.

• Weight is the same as mass.

• Weight is always opposite to drag.

In what way do the propellers on a quadcopter rotate?

• All four rotate clockwise

• Three rotate in one direction and the fourth rotates in the opposite direction to counteract the torque.

• Two opposing propellers rotate clockwise and the other two rotate clockwise.

• Two propellers on one side rotate clockwise and the two on the other side rotate counter clockwise.

Roll occurs about which quadcopter axis?

• Lateral

• Longitudinal

• Diagonal

• Vertical

How would you get a quadcopter to roll and move right?

• Decrease the front motors' speed.

• Increase the speed of the CW motors.

• Increase the speed on the left motors.

• Increase the speed on the right motors.
