25/26 Unit 6: Motion

Front

position

Back

refers to the location of an object in space relative to a reference point.

Front

reference point

Back

is a fixed point used to determine the position of an object.

Front

distance

Back

is the total length of the path traveled by an object, regardless of direction.

Front

displacement

Back

is the straight-line distance between the initial and final positions of an object, including direction.

Front

motion

Back

is the change in position of an object over time.

Front

speed

Back

is the rate at which an object covers distance, calculated as distance divided by time.

Front

vector

Back

is a quantity that has both magnitude and direction, such as displacement or velocity.

Front

velocity

Back

is the rate of change of displacement, including direction.

Front

speed (velocity) vs. time graph

Back

shows how the speed or velocity of an object changes over time.

Front

initial velocity

Back

is the velocity of an object at the start of its motion.
