3rd grade Forces and Interactions
Forces that do not sum to zero can cause changes in the object s speed or direction of motion PS2 B: Types of Interactions Objects in contact exert forces on each other 1,2,3,4,6 3-PS2-1 Plan and conduct an investigation to provide evidence of the effects of balanced and unbalanced forces on the motion of an object 1,2,3,4,5
Forces and Interactions - slcsus
Forces and Interactions Forces and Interactions is geared for third-grade students and focuses on the ability of student to: • determine the effects of balanced and unbalanced forces on the motion of an object • recognize the cause-and-effect relationships of electric or magnetic interactions between two objects in contact with each other
9 FORCES AND INTERACTIONS
9 FORCES AND INTERACTIONS What can force do to an object's motion? Objectives: • Recognize that force is a push or a pull • Recognize that forces have magnitudes (strengths) and directions • Discover that a force applied to an object will change the object's direction • Describe the key idea of Newton's first law of motion
Forces & Interactions - STEM Materials
Forces and Motion, students should be able to describe that forces have both strength and direction Students will demonstrate their understanding of this DCI by creating free-body diagrams to represent the forces acting on objects using arrows with varying direction and magnitude Teacher Demonstration: • Place an object (ex apple) on a desk

Intermolecular Interactions - Harvard University
The strongest interactions are between ions Ionic interactions are attractive interactions that occur between oppositely charged ions, that is, atoms that carry a charge that is at least equal to the full charge of a proton or electron Because ionic interactions involve the most charge, they are the strongest intermolecular interactions that occur
