- How are force and motion connected?
- How do you measure the motion of an object?
- How can we model the relationship of position, motion, direction and speed?
- How can you describe an object’s position?
- How does a change in mass affect the motion of objects?
- How does a change in force affect an object’s motion?
- How does momentum affect the motion of an object?
- How can you predict the direction an object will travel?
Vocabulary
- Distance - the length of a line between two points
- Motion - a change in an object’s position
- Direction - the path that a moving object follows
- Speed - a measure of how far an object moves in a certain amount of time
- Distance-time graph - a line graph that shows an object’s motion, with time on the x-axis and distance on the y-axis
- Force - a push or a pull
- Balanced forces - equal forces in opposite directions; cause an object to remain in place or moving at a constant speed
- Unbalanced forces - forces that cause an object to start moving, stop moving, or change direction
- Mass - the amount of matter an object contains
- Friction - a force that acts between surfaces that touch each other
- Gravity - a force that pulls objects toward each other
- Matter - anything that has mass and takes up space
- Air Resistance - a force that acts against the pull of gravity
- Position - the location of an object
