Vocabulary

 I can learn about how:

• changing how something moves by adding force
• motion stops when forces of the same strength are applied in opposite directions or when friction acts upon an object
• a force has strength and direction that will determine how it affects an object's speed and/or direction of motion
• gravity is a force with strength and direction and pulls objects down
• I can predict future motions of an object by observing its regular patterns of motion
• magnets cause a push or pull force on some materials and not others
• the forces of magnets decrease as distance between magnets increase
• magnets can be used to solve problems
• electrically charged objects can exert a force on other objects
•
