d. planting seeds
a. force and motion
What is a change in position called?
Motion
What is the force that pulls objects toward other objects? It keeps us on earth.
Gravity
What is the word we use to describe how fast an object is moving?
Speed
T OR F? Position is a place or location of something relative to another object.
