Vehicles Motion

FORCES, Balance & Unbalanced - Words & Definitions

Action A force exerted by 1 object on a 2nd object.
Friction The force that opposes motion.
Gravity The force of attraction between objects.
Net force The overall force acting on an object.
Normal The force that comes from the surface on which an object is located
Reaction The = but opposite force exerted by the 2nd object back on the 1st object in response to an action force
Balanced Forces opposite in direction & have = magnitude.
Balanced EXAMPLE: Example: When our car wasn’t moving it produced a net force of 0 due to friction and a force that were balanced.
Unbalanced Forces that don’t produce a net force of 0.
Unbalanced EXAMPLE: Example: When our car was just leaving the baseline, the magnitude of the car (weight) was to powerful to have friction to slow it down. The magnitude may also change the direction of the car causing it to veer.
