MD.5.0. Physics: Students will use scientific skills and processes to explain the interactions of matter and energy and the energy transformations that occur
5.A.1. Mechanics: Cite evidence from observations to describe the motion of an object using position and speed.
5.A.1.b. Using information from multiple trials, compare the speeds (faster or slower) of objects that travel the same distance in different amounts of time.
5.A.1.c. Using information from multiple trials, compare the distances that objects moving at different speeds travel in the same amount of time.
5.A.2. Mechanics: Explain that changes in the ways objects move are caused by forces.
5.A.2.a. Observe and describe the way an object's motion changes in a variety of situations (rolling a ball, bouncing a ball, dropping a yo-yo, winding up a toy, etc.) and identify what may have caused the change.
5.A.2.b. Describe changes in the motion of objects as they move across different textured surfaces and suggest possible causes for the change.
5.A.2.c. Observe and describe that objects fall to the ground unless something holds them up (gravity).
