The specific standards are:
PS2.A: Forces and Motion
Pushes and pulls can have different strengths and directions. (KPS2-1),(K-PS2-2)
Pushing or pulling on an object can change the speed or direction of its motion and can start or stop it. (K-PS2-1),(K-PS2-2)
PS2.B: Types of Interactions
When objects touch or collide, they push on one another and can change motion. (K-PS2-1)
PS3.C: Relationship Between Energy and Forces
A bigger push or pull makes things speed up or slow down more quickly. (secondary to K-PS2-1)
