Web Quest – Newton’s Laws of Motion
40 points
Directions:
 Go to “Faculty and Staff” and click on my name to access my Wiki
 Click on the folder on the left hand navigation bar titled, “Webquests”. Then click on “Newton’s webquest”
 Do the Webquest by following the directions and clicking on the links that will take you to different websites.
BALANCED AND UNBALANCED FORCES

Force is measured in units known as Newtons (Named for Sir Isaac Newton)
1. What is the net force when no forces are acting on an object?
2. Draw a diagram showing a force of 5N acting on an object.
3. Draw a diagram showing 2 forces acting on an object, but with a total net force of zero.
4. How do you find the total net force if 2 forces are acting on an object in opposite directions?
5. Draw a diagram showing 2 forces acting on an object in opposite directions with a total net force of 3N to the left.
6. How do you find the total net force if forces act on an object in the same direction?
7. Draw a diagram that shows 2 forces acting on an object in the same direction with a net force of 14N to the right.

THE LAWS
12. What is Newton’s first law?
13. The website gives both the actual law and also puts the law in simple language. Write what Newton’s first law is in simple
language from the website or put it into your own words.
14. What is Newton’s second law?
15. Now write it in simple language.
16. What formula represents Newton’s second law of motion?
17. What is Newton’s third law?

Check your understanding of Newton’s Laws of Motion
23. Which has more inertia – a 2,750 gram object or a 2,500 gram object?
24. Newton’s second law states that to increase acceleration, you:
a. increase force
c. increase mass
b. decrease force
d. increase inertia
25. An action force and its reaction force are:
a. equal in size and direction
b. equal in size and opposite in direction
c. different in size but in the same direction
d. different in size and direction
26. John pulls a box with a force of 4 N, and Jason pulls the same box from the opposite side with a force of 3 N. Ignoring
friction, which of the following statements is true?
a. the box moves toward John
b. the box moves toward Jason
27.
c. the box does not move
d. there is not enough information to
determine if the box moves.
Directions: Mark each of the following situations as an example of Newton’s First (1st ), Second (2nd ) or Third (3rd)
Law.
a. Rockets are launched into space using jet propulsion where exhaust accelerates out from the rocket and the rocket
accelerates in an opposite direction.
b. A soccer ball accelerates more than a bowling ball when thrown with the same force.
c. A magician pulls a tablecloth out from under dishes and glasses on a table without disturbing them.
d. A student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up.
