Newton's First Law
Inertia
Term | Definition |
---|---|
Balanced force | all forces acting on an object are equal and there is no movement |
time | distance divided by speed |
distance | how far an object goes |
speed how fast an object moves or the distance it moves in a given | how fast an object moves or the distance it moves in a given |
velocity | how fast and what direction an object goes in |
vector | quantity that has both size and direction |
Newtons first law | the law of inertia says that an object in rest stays in rest and an object in motion stays in motion |
mass | a measure of the amount of matter in an object |
inertia | An objects resistance to change its motion |
force | any push or pull that can change motion |
Net Force | combination of all forces in an object |
Unbalanced Force | forces that are acting on an object are not equal and cause movement |
position | an object or place’s location |
reference point time | a location to which you can compare other locations |
motion | a change in position and location |
acceleration | the rate at which velocity is changing |
