speed, velocity, and acceleration

how can you tell if an object is in motion?

if the object’s distance from another object is changing

what is a reference point?

a place or object used for comparison to determine if something is in motion

what is the difference between speed and velocity m?

speed covers the distance an object travels per unit of time, velocity is only the speed in one given direction

what is the difference between average and instantaneous speed?

average speed is total distance/total time

instantaneous is the rate at which an object is moving at a given instant in time

what is in the magic triangle?

distance (top) speed (bottom left) time (bottom right)

what is the equation for acceleration?

final speed - initial sped/ time

what are examples of acceleration?

increasing speed, decreasing speed, changing direction

what are the units of acceleration
