| Question | Answer |
|---|---|
| change of speed or direction | accelation |
| distance an object travels in certain amount of time and distance | speed |
| both and direction | velocity |
| a force is a push or pull | force |
| the strength of a force is measured in the SI unit called the newton | newton |
| the combination of all forces acting on an object is called the net force | net force |
| acting on an object result in a net force and cause a change in the object motion | unbalanced force |
| acting on one object in opposite directions are called balanced forces | balanced force/Equal forces |
| the force that two surfaces expert on each other when they rub together (Slows things down) | friction |
| object does not move | static friction |
| 2 solid surfaces slide over each other | sliding friction |
| when an object rolls across a surface | rolling friction |
| solid object moves throw a fluid (Air/Water) | fluid friction |
| a force that pulls a object towards each other | gravity |
| increases the force as of gravity increases | mass |
