=forces and motion facts=


 * newton** was a scientist that lived long ago. without gravity we would all be spinning off the earth and in outer space. there are pushes and pulls that we cannot see. it takes //more force// for an object that has more //mass//, but //less force// for an object that has //less mass//. objects can weigh the same its because they have the //same amount of mass.//

__speed-__ a measurement of distance over time. __velocity-__ measurement of distance over time but also includes direction. __balanced forces__- are forces that have a net force of zero. __unbalanced forces__- have a net force that is not zero.
 * examples of gravity**

__balanced forces__- do not change the motion of objects. __unbalanced forces__- do change the motion of objects. __position__- location of an object. __thrust__- moves an object forward. __drag__- is the position of thrust. __lift__- force and pressure from the water.
