Question | Answer |
---|---|
distance | how far you have traveled two positions. It 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. |
Scalar | quantity that only requires magnitude (how big) |
vector | quantity that requires both magnitude and direction |
speed | how fast something is moving = D/T |
Velocity | Rate at which position changes Displacement/ Time |
Newton's first law | The law of inertia, an object at rest will stay at rest, object will stay in motion unless a force pushes an object. |
Mass | a measure of the amount of matter an object has |
inertia | the resistance an object has to change its motion |
Force | any push or pull that can cause a change in an objects motion |
Net force | the combination of all forces and an object |
Balanced forces | When the net force is both horizontal and vertical direction at 0N% |
Unbalanced forces | When the net force is both horizontal and vertical direction and not at a 0N% |
Gravatational force | A non-contacr force between two objects that is most apparent close to a large object. |
