Weight The measurement of the pull of gravity on an object
Pull A force to bring something toward someone or something
Push A force to move something away from something or someone
Inertia Matter's resistance to change in motion
Acceleration The rate at which the speed of a moving object changes over time
Motion Movement from one place to another in a certain amount of time
Friction A force that slows down movement
Speed The rate at which someone or something moves or travels
Distance An amount of space between two things or people
Time Continued progress in events from the past, present, and future
Force Push or pull applied to an object
Position The location of any object
Axis The two perpendicular lines on a coordinate grid
Balanced Force Forces that are equal causing an object to stop moving
Unbalanced Force Forces that are not equal causing an object to move or change motion
Direction a course along which someone or something moves
Velocity the speed of something in a given direction
Air Resistance the force acting on an object that is moving through air flowing in the opposite direction
Momentum mass in motion
Resist to fight or oppose
Declaration Moves slower
Newton's First Law an object in motion stays in motion unless a force acts upon it
Newton's Second Law the rate of momentum is directly and proportional to the force applied to the object and takes place in the direction in which force is applied
Newton's Third Law for every action (force) there is an equal and opposite reaction (force)
