N1st Law and Motion
Term | Definition |
---|---|
Distance | How far you have traveled between two positions. its is always positive. It is a scalar quantity |
Displacement | Change in position it is the straight line distance between your starting position and ending position |
Salar | Quantity that only requires magnitude |
Vector | Quantity that only requires both magnitude and directions |
Seed | How fast something is moving |
Velocity | Rate at which position changes. it is equal to distance divided by time |
Newtons First law | AKA law of inertia an object at rest will stay at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by a unbalanced force. |
Mass | a measure of the amount of matter an object contains. Also a measure of the amount of inertia an object has. |
Inertia | The resistance an object has to changes in motion. |
Force | Any push or pull that can cause change in motion. |
Net force | The combination of all the forces on a object. |
Balanced force | When the net force in both the horizontal and vertical directions is 0 N. These cause motion to remain uncharged |
Unbalanced force | When the net force in both horizontal and directions is 0 N. These cause motion to change. |
Gravitational force | A non-contact force between 2 objects that is the most apparent close to a large object such a planet. |
Applied force | The support forces exert upon an object that is in contact with another stable object it is in the direction of push or pull. |
Normal force | A contact force that is exerted by a surface against a object that is pressing against an object. |
Tension force | contact force exerted by a taunt string rope or wire on a object. |
Friction force | the force exerted by a surface as a object moves across it or makes it. |
Air Resistance | A special type of friction force that acts upon objects as they travel through the air. |
Spring | a contact force exerted on a force. |
thrust | a contact force that is exerted in the opposite direction. |
