TermDefinition
Gravity the force that attracts an object toward the center of the Earth, or toward any other physical body having mass
Force push or pull applied to an object
Push to use force to move someone or something away from you
Pull to hold onto and move someone thing toward yourself
Friction force that opposes movement between touching surfaces and always acts against
Newtons First Law an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force
Mass is a measurement of the amount of matter something contains
Weight is the measurement of the pull of gravity on an object
Motion the action or process of moving or of changing place or position; movement
Inertia the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force
Position the rate at which someone or something moves or travels
Axis the place where someone or something is in relation to other people or things
Unbalanced Force are not equal, and they always cause the motion of an object to change the speed and/or direction that it is moving
Acceleration the rate at which the speed of a moving object changes over time
Direction a course along which someone or something moves
Velocity the speed of something in a given direction
Air Resistance the forces that are in opposition to the relative motion of an object as it passes
Momentum the quantity of motion of a moving body, measured as a product of its mass and velocity
Resist withstand the action or effect of
Deceleration reduction in speed or rate
Newton’s Second Law describes the affect of net force and mass upon the acceleration of an object
Newton’s Third Law for every action there is an equal and opposite reaction
