Title – Looking for Newton
By – Joe Wier
Subject – Science
Grade Level – 7-12

Directions: Look up each web address and either fill in the blank or answer the question about each address. If you have time left over then try to find five interactive Newton’s Laws web sites.

1. We have an intuitive idea of what a “force” is. We may think of a force as a __________________.

2. That is the very ________________________that is described by Newton’s First Law. An object continues in motion simply because it was in motion if there are no forces acting on it to change its motion.

3. A force of _________ unit will give an object of 1.0 kg mass an acceleration of 1.0 m/s/s ; this force is known as: ONE NEWTON (1.0 N) 1 N = ( 1 kg ) ( 1 m/s/s )

4. A surface can always supply a ___________force, perpendicular to the surface. However, a surface quite often also supplies a fiction force parallel to the plane. Friction forces always oppose the motion — or prevent the motion.

1. Examples in the “inertia” section state____________________________________.

2. “How is force measured?” section states __________________________________
3. Answer the Force Challenge! Section question

1. A rocket in its simplest form is a ___________________a gas under pressure. A small opening at one end of the chamber allows the gas to escape, and in doing so provides a thrust that propels the rocket in the opposite direction.

2. If you are ___________in a chair, you can be said to be at rest.

2. An __________________must be exerted for a rocket to lift off from a launch pad or for a craft in space to change speed or direction (first law)

1. The law of inertia is most commonly experienced when_________________.

2. What happens to the guy in the car and the wall picture?

3. If the motorcycle were to___________, then the rider in motion would continue in motion.

4. What happens to the ladder in the ladder and truck picture?

1. Force is measured in ____________. A Newton is the amount of force needed to push 1 kg with an acceleration of 1m/sec2.

2. This explains why a rocket works in__________________.

1. In equation form, if we call the force “F”, the object’s mass “m” and the acceleration “a”, then Newton’s Second Law is simply ______________________________________.

1.Newton’s Laws – a tale of _______________and ______________________________.

2. Every body continues in its state of ______________or of uniform motion in a straight line unless compelled by some external force to act otherwise.

1. Read and take the quiz2.

1. write down five of the demos that you viewed on this page. (just the name)
