Rotational speed is calculated by the number of times that an object rotates over the time it rotates. How much do you understand chapter 8 where we got to understand how to calculate this type of speed. Do you believe you understood the introductory part? Take up the physics practice quiz below and test your understanding before the final exam is upon us. All the best and keep practicing what you learn.
The property of an object to resist change.
The property of an object to resist change in a linear motion.
The property of an object to resist change in a rotational motion.
A measurement that measures distance travelled per unit of time in circular motion.
A measurement that measures the number of rotation per unit of time in a circle motion.
A MEASUREMENT THAT MEASURES HOW MUCH FORCE WAS APPLIED TO A ROTATION.
