Force and Motion

Position Location of an object
Motion An object's change in position relative to a reference point
Reference Point A place or object to which another location is compared
Displacement The straight-line distance between a starting point and an end point
Speed The measure of how quickly distance changes with time
Average Speed Motion over a period of time
Instantaneous Speed The speed of an object at a specific instant in time
Velocity Speed combined with the direction of motion
Vector Physical quantity that has size and direction
Acceleration Measure of how quickly velocity changes
Newton's 2nd Law Acceleration of an object depends on the mass of the object and the net force applied
Net Force The combination of all the forces acting on the object
Balanced Forces A set of forces that cancel one another so that there is no overall force on an object
Unbalanced Forces A set of forces acting on an object that do not cancel each other out
Potential Energy Stored energy or energy of position (PE=mgh)
Kinetic Energy Energy of movement (KE=mv-squared)
