Newtonian Mechanics and Forces Questions

Multiple choice

Which of the following is not a fundamental force in physics?

  1. Gravitational force

  2. Electromagnetic force

  3. Strong nuclear force

  4. Weak nuclear force

  5. Centrifugal force
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Centrifugal force is not a fundamental force in physics. It is an inertial force that arises due to the rotation of a frame of reference.

Multiple choice

Which of the following is an example of a practical effect?

  1. A spaceship flying through space

  2. A car exploding

  3. A character transforming into a monster

  4. A dragon breathing fire
