In a falling weight system, what force give the push or pull needed to move the vehicle?
friction, gravity, washers, or the rubber band?
the washers
100
In order to make a vehicle move, you would wrap the rubber band around the rear azle. Which way woud you wrap the rubber band around the axle?
Over the axle and then counterclockwise around it
100
What are two things you learned from our Motion & Design Unit?
Miss Hayden will decide on points distributed
200
What is energy?
the ability to do work or o produce a change
200
True or False
Is it helpful to have multiple views of the vehicles design? Why or why not?
True - it is helpful so you can see the vehicle from different angles and it helps you know where parts are if you are unable to see them from different angles.
200
When using the falling-weight system, if you increase the force (by increasing the number or washers), what happens to the vehicles speed? Why?
The speed increases becuase the force is greater
200
Fill in the Blank: The more turns of the rubber band around the axle or turns of the propeller, the more ____________________ energy is stored.
potential or stored
200
In your own words, explain a situation where friction effects an objects movement.
Miss Hayden will determine points distributed.
300
What is potential energy?
built up energy before being released
300
Within the cars that we have built from technical drawings, did we always use the rubber wheels? Why or Why Not?
No, using rubber wheels for all the wheels would cause more friction
300
If a vehicle has a heavy load it needs (a lot, a little, no) force (washers)
It needs a lot of force - more washers need to be added
300
Fill in the blank: The more turns of the rubber band, the _______________ (greater or less) distance the vehicle will travel.
Why?
greater
300
What is the difference between potential energy and kinetic energy?
Potential energy = Stored energy & Kinetic energy = movement
400
What is kinetic energy?
the energy of movement
400
True/False: When designing a vehicle you shouldn't look at the technical drawing because it will only confuse you.
False
400
If your vehicle has one block (small load) how would you get it to move slower.....
1 washer, 5 washers, or 10 washers
1 washer so then the force isn't as large causing the car to move slower
400
____________ (kinetic, stored, friction) is another force and it can slow the vehicle down and even bring it to a stop.
friction
400
Weight on a vehicle is also known as _______________________________.
LOAD
500
What is friction?
objects rubbing against one another causing the object to move faster or slower based on the amount of friction
500
True/False: When building a vehicle it is important to gather your materials before you start building.
True
500
If you had a car with 3 blocks as it's load, how would you make it move the slowest?
1 washer, 5 washers, 10 washers
1 washer
500
True or False: The more turns of the rubber band of the propeller-driven vehicle, the more potential energy is stored.
True
500
True/False: You are not using force if the object isn't moving.
True, you are only distrubuting force when the object moves.
