Lesson: Systems of Objects Physics

In this lesson, we will learn how to analyze the changes in the properties of systems of objects and the forces involved in such changes.

Q1:

A system consists of two identical objects, as shown in the diagram. The objects exert repulsive forces on each other. At a time 𝑡, the objects approach each other moving at velocities vv=. The objects collide, and at a time 𝑡 they recede from each other moving at velocities vv=, where vv> and vv>. The separation of the objects is the same at 𝑡 and 𝑡.

Which of the following properties of the system are different at 𝑡 and 𝑡?

Which of the following types of forces explains any changes to the system?

Q2:

A system consists of two identical objects, as shown in the diagram. The objects exert negligible forces on each other. At a time 𝑡, the objects approach each other, moving at velocities vv=. At a time 𝑡, the objects recede from each other, moving at velocities vv=, where vv= and vv=. The separation of the objects is the same at 𝑡 and at 𝑡.

Which of the following properties of the system are different at 𝑡 and 𝑡?

Which of the following types of forces explains any changes to the system?
