Force & Motion
- force is a push and
pull
- force is what makes things
move.
- motion is what makes things go fast or
slow.
- Forces are a big part of physics. Physicists devote a lot of time to the study of forces that are
found everywhere in the universe.
- The forces could be big, such as the pull of a star on a planet. The forces could also be very small,
such as the pull of a nucleus on an electron. Forces are acting everywhere in the universe at all
times.
- If there is more than one force acting on an object, the forces can be added up if they act in the
same direction, or subtracted if they act in opposition
