Distance and Displacement

Distance - ________

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

• Difference from starting to ending point.

• Distance is the measurement of time taken to travel from one place to another.

Displacement - _________

• Displacement is the straight-line distance from the starting point to the ending point, along with the direction.

• Displacement is the total path length traveled, regardless of direction.

• Displacement is the amount of time taken to travel from one point to another.

• Displacement is the speed at which an object moves from one place to another.

A runner at a track meet completes exactly one lap around a 400 m track. distance = _____ displacement = ______

• distance = 400 m displacement = 0 m

• distance = 0 m displacement = 400 m

• distance = 400 m displacement = 400 m

• distance = 0 m displacement = 0 m

The runner completes exactly 2 laps around a 400m track. distance = t_______ displacement = _______

• distance = 800 m displacement = 0 m

• distance = 400 m displacement = 400 m

• distance = 800 m displacement = 400 m

• distance = 400 m displacement = 0 m

For any object in motion, distance is always _______ displacement.

• less than

• less than or equal to

• equal to

• greater than or equal to

A swimmer swims a half lap (one length of the pool), moving from the left end to the right end of a pool that is 50 meters long. Distance = _____ Displacement = ______

• Distance = 50 meters Displacement = 50 meters

• Distance = 25 meters Displacement = 25 meters

• Distance = 100 meters Displacement = 0 meters

• Distance = 50 meters Displacement = 0 meters

A swimmer swims an entire lap, moving from the left end to the right end and back again to the left end in a pool that is 50 meters long. Distance = __________ Displacement = __________

• Distance = 100 meters Displacement = 0 meters

• Distance = 50 meters Displacement = 50 meters

• Distance = 0 meters Displacement = 100 meters

• Distance = 100 meters Displacement = 50 meters

For a typical day in your life, from the time you get out of bed in the morning to the time you climb back into your bed at night, which of the following is true about your distance traveled and displacement?

• Distance is greater than displacement.

• Distance is less than displacement.

• Distance and displacement are always equal.

• Displacement is always zero.

It is possible for your lifetime displacement to be equal to zero.

• Yes, if you return to your starting point.

• No, it is never possible.

• Only if you never move.

• Only if you move in a straight line.
