Motion and Speed Test Study Matieral

Speed is the ratio of the distance an object moves to

• The amount of time needed to travel the distance

• The direction the object moves

• the displacement of the object

• the motion of the object

• 42 km/h

• 148 hm/h

• 1060 km/h

A horizontal line on a distance-time graph means the object is

A distance-time graph indicates that an object moves 100 m in 4 s and then remains at rest for 6 s. What is the average speed of the object?

• 50 m/s

• 25 m/s

• 10 m/s

• 100 m/s

Displacement vectors of 6 km south, 3 km north, 4 km south, and 5 km north combine to a total displacement of

• 9 km south

• 14 km west

• 2 km south

• 18 k north

Speed between 2 points that does not change is called?

• average speed

• constant speed

• instant speed

• minimum speed

The equation which correctly represents the relationship between speed, distance, and time is?

• v= t x d

• d= v x t

• v= t/d

• d= v/t

The slope of a distance vs. time graph is equal to:

• Distance

• Speed

• Acceleration

• area

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

• a position

• a reference point

• a constant

• velocity
