Speed, Distance Time Graph, Point of Reference

How much time is required for a bicycle to travel a distance of 100m at an average speed of 2 m/s?

• 0.02 s

• 50 s

• 100 s

• 200 s

A student is a passenger in the front seat of a moving car. Which object is the best frame of reference for the student to determine how fast the car is moving relative to the ground?

• A person sitting in the backseat of the car

• A truck traveling in the lane next to the car

• The driver sitting next to the student

• A stop sign on the side of the road

The graph relates speed and time of four cars (1, 2, 3, and 4) traveling along a straight highway. Which two cars move with zero acceleration?

• A) 1 and 4

• B) 2 and 3

• C) 1 and 2

• D) 3 and 4

Look at the velocity-time graph below. According to the graph, the acceleration of the object is:

• constant

• decreasing

• increasing

• zero

An object moves at a constant speed. Which graph best represents the motion of the object?

• 
• 
• 
• 

Match the examples as acceleration and not acceleration.

Groups:

(a) Acceleration

,

(b) Not Acceleration

• A car slows down when approaching an intersection

• A car increases in speed from 10 km/hr in 5 seconds

• A car is stopped at a read light

• A car maintains its speed of 15 km/hr when making a right turn

The graph shows the movement of an object at several points in time. What is the average speed of the object?

• 0.5 meters per minute

• 2 meters per minute

• 25 meters per minute

• 50 meters per minute

The graph shows the distance an object traveled over time. Which line segment represents the time interval during which the object was moving at a positive constant speed?

• segment W

• segment X

• segment Y

• segment Z
