Unbalanced forces | Forces on an object that cause change in the motion of the object. |
Net force | The sum of all the forced acting on an object |
At rest | The state of an object when it not in motion |
Motion | The change in an position with respect to time and in comparison to the position of other objects used as reference point. |
Speed | The rate of change of position or distance traveled with respect to time units in which speed is measured are expressed as distance per time(example:meters per second). |
Direction | A straight path that an object can move along. |
Friction | Force that opposes the motion of one surface across another. |
Frame of reference | A system that used axes or background objects to measure the position or movement of an object. |
Velocity | Measurement of speed and direction of an object. |
Acceleration | The rate of change in an object's speed. |
