TermDefinition
Displacement The measured distance of an object from its starting point to its final location
Inertia Matter's resistance to changing its state of motion
Terminal Velocity The greatest amount of motion that an object can have
Thermal Energy Heat energy
Net Force The product of combined forces
Resistance Another word for Inertia
Constant The motion when all forces acting on an object are balanced
Negative Acceleration Slowing down
Velocity Speed and direction
Force Mass x Acceleration
Joules The units to measure Energy and Work

Change A word that describes what Acceleration is.
Friction A force that opposes motion
Reaction According to Newton's 3rd law; Action forces are always paired equally with _________ forces
Unbalanced forces What causes acceleration?
Speed Distance per unit of time
Kinetic Energy The energy of motion
Potential Energy Stored energy
Gravity A force that comes from all matter
Acceleration The result of Net force applied to an object
Deceleration The result of a Net force applied in the opposite direction of an object in motion
Drag force A force in fluids that slows moving objects
