a change in an object's position with respect to time and in comparison to other objects; a change in the position, direction, or speed of an object

three laws that describe the relationship between an object and the forces that act on it

a force that causes objects with mass to attract each other

where an object is located in space

a straight path that something could move along

the rate of motion;

a push or pull that causes an object to move, stop, or change direction

to use force to cause something to move closer

to use force to move away

separate forces that combine to cancel each other out or make a net force of zero

a force that is not canceled out by another force and causes the motion of an object

a force that resists the motion of two surfaces sliding across one another

a change in position or location

the energy stored in an object that is not moving

energy of motion
