Question 1 of 10
1. Question
Al these questions is about the following graph:
You should answer with a magnitude and a unit. Don’t forget to write a space between the magnitude and the unit. Write metres as m and metres per second as m/s. Use the ordinary minus sign ( on the numerical keyboard on a PC) for negative numbers.What is the initial position? That is, how far from the origin is the object?
Correct
Incorrect
Hint
Don’t forget a space between the magnitude and the unit.

Question 2 of 10
2. Question
What position is the object at after 2 s?
Correct
Incorrect

Question 3 of 10
3. Question
What is the velocity at t=2 s?
Correct
Incorrect
Hint
 The velocity at a particular point is the same as the slope of the line in an s/tgraph.
 Don’t forget that we are moving in a negative direction, i.e. closer and closer to the origin.

Question 4 of 10
4. Question
What is the speed at t=2 s?
Correct
Incorrect
Hint
Rememberer that speed is a scalar, i.e. just a number without any direction indication. The velocity 2 m/s and 2 m/s does both correspond to the speed 2 m/s.

Question 5 of 10
5. Question
What is the distance travelled over the first 4 s?
Correct
Incorrect
Hint
 What position did the object have initially?
 What is the position at t=4 S?
 So how far have it moved?

Question 6 of 10
6. Question
What is the displacement over the first four seconds?
Correct
Incorrect
Hint
In what direction did we move?

Question 7 of 10
7. Question
What is the speed at t=8 s?
Correct
Incorrect
Hint
 Does the object move at all?
 Don’t forget the unit.

Question 8 of 10
8. Question
What is the velocity at t=5.5 s?
Correct
Incorrect
Hint
 velocity =change of position / change in time.
 The velocity at a point along a straight line in an s/t graph = the average velocity over the line = the slope of the line.

Question 9 of 10
9. Question
What is the total distance travelled over the whole 15 s?
Correct
Incorrect
Hint
Add all the distances.

Question 10 of 10
10. Question
What is the average speed over the complete movement?
Correct
Incorrect
