/ I / the Phenomenon |
|
some Objects can exert forces on one another without even being in contact.
[CER] DISCUSSION QUESTION:
Can objects exert forces on one another without touching? Make a claim then gather evidence to support and justify your claim throughout this lesson. |
/ Ii / Investigate
1. Static Fanatic - investigate the power of static electricity.
2. Magnificent Magnets - investigate the power of magnets. 3. The Bubble Levitator - learn how the Force Levitator levitates the bubble. |
/ Iii / Level Up!
During this lesson you will learn more about the underlying forces that explain the variety of interactions we observed between objects.
✎Notes:
- Objects in contact exert forces on each other (friction, elastic pushes and pulls).
- Electric, magnetic, and gravitational forces between a pair of objects do not require that the objects be in contact—for example, magnets push or pull at a distance.
- The sizes of the forces in each situation depend on the properties of the objects and their distances apart and, for forces between two magnets, on their orientation relative to each other.
- The gravitational force of Earth acting on an object near Earth’s surface pulls that object toward the planet’s center.
