Force - -Any influance that tends to accelerate an object; a push or pull; measured in newtons; vector quantiy -Applied Force - -An external force -Friction - -Force that acts to resist the relative motion (or attempted motion) of objects or materials that are in contact -Net Force - -Combination of all the forces that act on an object -Support Force - -Upward force that balances the weight of an object on a surface -Weight - -The force that an object exerts on a supporting surface (or, if suspended, in a supported string) - often, but not always, due to the force of gravity -Balanced Forces - -Equal in size or magnitude/ opposite direction. Do not cause a change in motion -Tension Forces - -Applied force that is an upward force but does not have support from the bottom. Ex: The rope on a tire swing -Inertia - -Sluggishness or apparent resistance of an object to change its state of motion. Measured in mass. -Vector Quantity - -Quantity in physics that has both magnitude and direction. Ex: Force, velocity, acceleration, torque, and electric and magnetic field. -Scalar Quantity - -Quantity in physics, such as mass, volume, and time that can be completely specified by its magnitude and has no direction -Headwind - -Wind going in the SAME direction as the other object in motion. -Tailwind - -Wind going in the OPPOSITE direction as
