|---|---|---|---|---|---|
| when an object changes position over time relative to a refrence point | motion

| The distance traveled divided by the time interval during which the motion occured | speed
🗑
|
||||
| the speed of an object in a particular direction | velocity
🗑

| the rate at which velocity changes over time; an object accelerates if speed, direction, or both change | acceleration
🗑
|
||||
| total distance/total time | formula for average speed
🗑
|
||||
| final velocity-starting velocity/ time it takes to change velocity | formula for average acceleration
🗑
|
||||
| a push or pull exerted on an object in order to change the motion of the object; force has size and direction | force
🗑
|
||||
| the si unit for force | newton
🗑
|
||||
| the combination of all of the forces acting on an object | net force
🗑
|
||||
| a force that opposes motion between two surfaces that are in contact | friction
🗑
|
||||
| when a force is applied to an object but doesnt move | static friction
🗑
|
||||
| friction between moving surfaces | kinetic friction
🗑
