Force
What is force?
A push or a pull
What is motion?
movement
What are the two types of energy that we have talked about in our small groups?
Kinetic and Potential Energy
What was the device we used to demonstrate the transfer of energy?
Newton's Cradle
What is the engineering and design process?
Ask, Imagine, Plan, Create, Improve
What forces acts on a boat in the water?
water
air
What is friction?
a barrier to motion that slows down an object
If someone is on top of a ski slope getting ready to go down, what kind of energy would this be?
Potential energy
Name three structures you created this class?
Slide, Rocket, boat, house, tower
When your teachers told you to sketch your designs, what part of the engineering and design process was this?
Plan
What forces act on a balloon?
gravity
air
What friction is involved when a ball is slowing down on a soccer field?
Grass
If a ball is moving on a soccer field, what kind of energy would this be?
Kinetic Energy
What school do your small group teachers go to?
Towson
If my slide did not work out correctly, what should I do in order to make it better?
You should IMPROVE your design, go back over what did not work well and figure out how to fix it.
A ball is lying on the floor. When will the ball move?
When a force acts on it.
Give an example of an everyday object that moves in a zig-zag motion?
possible answer: skier
If the skier is now moving down the slope, what type of energy would this be?
Kinetic and Potential energy
Why is it better to have traction on tires rather than a smooth tire?
It creates friction so that the tire is able to grip the ground better and we are able to make a stop or slow down.
