What is a Force?
A push or a pull
100
What is Newton's 1st Law of Motion?
An object at rest will stay at rest. An object in motion will stay in motion, unless acted on by an unbalanced force.

What is the oldest and simplest form of a bridge?
What is a Beam Bridge
100
What is formula for Speed?
What is Speed = Distance divided by Time
100
What instrument do you use to measure mass?
A (triple beam) balance
200
What is the Unit if Measurement for Force?
A Newton

Newton's 1st Law of Motion is also known as this.
What is the Law of Intetia
200
What is the geometric shape that helps to give stability and strength to Truss Bridges
What is a Triangle
200
Define acceleration
Acceleration is the change of an object speed or direction
200
What instrument do you use to measure Force?
What is a Spring Scale
300
All Force is described as being one of two categories. What are these categories.
What is a Balanced or Unbalanced Forec
300
What is Newton's 2nd Law of Motion?
What is Force = Mass x Acceleration
300
Which force acts to push the beam bridge towards the top center?
What is Compression

Mr. Baumann drives his car 100 kilometers. It took him 4 hours. What is his Average speed?
Average Speed = Total distance traveled divided by total time. 100KM / 4 hours = 25Km/hour
300
Which variable is always plotted on the Y - Axis?
What is the Dependent Variable
400
Friction is a type of force. What are the 4 types of friction?
What is Static, Rolling, Sliding and Fluid Friction
400
What is Newton's 3rd Law of Motion?
For every action there is an equal and opposite reaction
400
What is the advantage of a Suspension Bridge vs. an Arch Bridge?
It can span a greater distance and hold a larger load
400
Mr. Baumann is driving in a circle. His speed is constant at 25 Km/hour. Is he accelerating? Why?
Yes he is accelerating. Even tough he is driving at a constant speed, he is changing direction as he drives in a circle.
400
What is the minimal amount of trials you need for a valid experiment?
What is 3

A 5 Kg object is being pushed by first a 2N force and then a 10 N force. Which force will push the object the furthest?
The 10 N force
500
What is weight?
It is the measure of the pull of gravity on an onject
500
What is the force that acts to twist a bridge?
What is Torsion
500
Does your mass or weight change if you are on the moon?
Your weight will change, but your mass always stays the same.

The results of an experiment yielded the following data 12,10,10 and 12 What is the average of these numbers?
Add the 4 numbers (44) Then divide this total by the number of Trials (44 / 4) = 11
