Term | Definition |
---|---|
temperature | the measure of the average kinetic energy of the particles in a material |
heat | the movement of thermal energy from a region of higher temperature to region of lower temperature |
conduction | is the transfer of thermal energy by collisions between particles in matter |
radiation | the of thermal energy by electromagnetic waves |
convection | the transfer of thermal energy by the movement of the particles from one part of a material to another |
vaporization | is the change of state from a liquid to a gas |
thermal conductor | a material in which thermal energy moves quickly |
thermal insulator | a material in which thermal energy moves slowly |
motion 2.1 | is the process of changing position |
reference point | the starting point you use to describe the motion or the position of an object |
distance | is the total length of your path |
displacement | is the distance between your initial, or starting, position of your final position |
speed | is the distance an object moves divided by the time it took to move that distance |
velocity | is the speed and direction of an object's motion |
acceleration | is the measure of the change in velocity during a period of time |
force 2.2 | a push or pull on an object |
contact force | is a push or pull applied by one object to another object that is touching |
noncontact force | a force that pushes or pulls an object without touching |
friction | contact force that resists the sliding motion between two objects that are touching |
gravity | is a noncontact attractive force that exists between all objects that have mass |
balanced forces | when the net force on an object is ON, the forces acting on it |
unbalanced forces | when the net force acting on an object is no O, the forces acting on the object |
