Distance and Displacement

Front

What is the definition of distance?

Back

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

Front

What is the definition of displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

True or False: The shortest distance between two points is a straight line.

Back

True

Front

If Scott travels north 5 miles and then west 3 miles, what is his total distance traveled?

Back

8 miles (5 miles + 3 miles)

Front

If Jerry walked from home to school (2 km) and then to the park (5 km), what is his total distance?

Back

7 km (2 km + 5 km)

Front

If Jerry's home is 2 km east of the school and he walks to the park which is also 2 km east, what is his displacement?

Back

0 km (he ends up at the same east-west position as he started)

Front

What is the formula for calculating the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

If a rectangle has a length of 5 m and a width of 3 m, what is its perimeter?

Back

16 m (2(5 m + 3 m))

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity (only magnitude), while displacement is a vector quantity (magnitude and direction).

Front

If a person travels 10 m north and then 10 m south, what is their total distance and displacement?

Back

Total distance = 20 m; Total displacement = 0 m.
