scooby motion

motion flashcards

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
