4) Use your free body diagram and the idea of centripetal acceleration to identify the mistake in each student's statement: Student 1: "The Moon is in space. Therefore, there cannot be any forces on the moon. That is why the moon stays up in the sky instead of crashing into the Earth." Student 2: "There should be two forces on the Moon: a gravity force toward the Earth and a centrifugal force pointing away from the Earth. Because these two forces are balanced the Moon does not crash into the Earth. Student 3: "There should only be one force on the Moon- the force of gravity toward the Earth. However, because the Moon is so far away, the force of gravity is too weak to move that much mass, that is why the Moon does not crash into the Earth."

The centripetal force of an object of mass is given by F(r)=mv^2 / r, where v is the speed of rotation and r is the distance from the center of rotation. Need help in explaing what concepts are being used and why it is important. Thank you Answer the following: Draw a graph or figure to represent this situation. Describe how the concepts from this module can be applied in this case. Find the rate of change of centripetal force with respect to the distance from the center of rotation. Provide another example of a scenario that involves the same concept.
A 1.5 kg mass is spun on a string in a horizontal circular path at a constant speed. a). Draw the free-body diagram for the mass. b). If the radius of the path is 0.5 m and the period of revolution is 0.25 s, what is the speed of the mass? c). Calculate the centripetal force that is keeping the mass in a circular path? d). What is the net force acting on the mass in the horizontal direction?
Identify the type of inertia being described by each of the following statements. Choose the correct answer from the box then shade the letter of your answer on the answer sheet provided. 1. When you stir coffee in a cup and stop, the swirling motion continues due to inertia. 2. When pedaling a bicycle and you stop pedaling, the bike continues going until friction or gravity slows it down. 3. If the wind is blowing, tree branches are moving. Fruits that fall from the tree will fall in the direction the wind is moving into because of inertia. 4. When pulling a Band-Aid off, it is better to pull it fast. Your skin will remain at rest due to inertia, and the force pulls the Band-Aid off. 5. If a car is moving forward it will continue to move forward unless friction or the brakes interfere with its movement. A. inertia of rest B. inertia of motion C. inertia of direction

Based on the data below: 1. How did the change in radius, while keeping everything constant, affect the stopper as it was spinning? 2. How did the increase in mass (number of stoppers), while keeping everything constant, affect the stopper as it was spinning? 3. How did the change in hanging mass (m2), while keeping everything constant, affect the stopper as it was spinning? 4. What are the implications of the percent error calculations between the calculated centripetal forces and the hanged masses for the following: i) TABLE A ii) TABLE B iii) TABLE C
