# SCIENCE TEST STUDY GUIDE: FORCES, MOTION, AND MAGNETS Test Date: Friday, October 18th ## Forces - **What is a force?** A force is a push or a pull. - **What is a push?** A push is a force that moves an object away from you. - **What is a pull?** A pull is a force that moves an object toward you. - **What are balanced forces?** Balanced forces are two equal forces that push or pull in opposite directions so that the object doesn't move. - **What are unbalanced forces?** Unbalanced forces are two forces that push and pull in opposite directions where one force is greater than the other so that the object moves. - **What is friction?** Friction is an invisible force that resists the motion of an object. - **What is gravity?** Gravity is an invisible force that pulls any object down, toward the Earth. ## Motion - **What is motion?** Motion is a change in the position of an object. - **What is a pattern of motion?** A pattern of motion is made when a moving object makes the same pattern again and again. ## Magnets - **What do all magnets have?** All magnets have a north and a south pole. - **What can all magnets do?** All magnets can attract (to pull toward) and repel (to push away, such as when two magnets when the same poles face each other). - **What is the invisible space where a magnet can exert its force on another object?** A magnetic field is the invisible space where a magnet can exert its force on another object. - **What are some problems that can be solved with magnets?** Examples of problems that can be solved with magnets include holding objects to a refrigerator, picking up small objects from the floor, and telling which way is north using a compass. - **What is something that is magnetic?** Iron is an example of something that is magnetic. - **Do magnets need to touch something to apply a force?** Magnets do not need to touch something to apply a force. - **What happens when two objects have the same charge?** When two objects have the same charge, they repel each other. - **What is the biggest magnet on our planet?** The biggest magnet on our planet is the planet itself: Earth.
