Word | Meaning |

Distance | How far you have traveled between two positions .it is a scalar quantity. |
Displacement | change in position,it is a straight line distance between you starting position and ending position. It is equal to final position minus initial positions it can be positive and negative . it is a vector quantity! |
Scalar | quantity that only requires magnitude (how big) |
Vector | quantity that requires both magnitude (how big) and directions |
Speed | how fast something is moving . it is equal to distance divided by time it is a scalar quantity |
Velocity | rate at which position changes . it is equal to displacement divided by time . it is a vector quantity |
Newtons First Law | AKA the law of inertia , an object at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force |
Mass | a measure of the amount of matter an object contains , Also a measure of the amount of inertia an object has |
Intertia | the resistance an object has to changes in its motion |
Force | any pull or push (interaction) that can cause a change in motion . An interaction between two objects |
Net force | the combination of all of the forces on an object |
Balanced Force | when the net force in both the horizontal and vertical directions is 0 N these cause motion to remain unchanged |
Unbalanced force | when the net force in both the horizontal and vertical directions is not 0 N these cause motion to change |
Gravitational force | a non contact force between two objects that is most apparent close to a large object,such as a planet |
Applied force | the support force exerted upon an object that is in a contact with another stable object it is the direction of the pull and push |
Normal Force | A contact force that is exerted by a surface and present whenever atoms are being cruched |
Tension force | contact force exerted by a taut rope |
Friction force | an object that moves or try to move |
Air Resistance/drag | a movement from air |
Spring force | |
Thrust | a movement that goes in the direction that wasnt met for |
