W = F x D
What is the formula for work?
100
This is the result when an object moves in the direction of applied force.
What is work?
100
The object moves in the direction of the force applied.
What happens when a force acts on an object?
100
This is the type of energy stored in food.
What is chemical?
200
Wash with this if acid splashes on your skin.
What is water?
200
Using a 3 kg box that is moved 5 m, results in this amount of work.
What is 15 N?
200
No work is being done if an object remains like this.
What is stationary?
200
Students want to raise a crate from the ground to a deck. They know it will be easier to move the crate along this object because it will reduce the force to raise the crate. Name the object.
What is an inclined plane?
200
This is the type of energy in movement.
What is mechanical?
300
Use this to measure liquid in mL.
What is a graduated cylinder?
300
There are ways to decrease the amount of work required to move objects. For example, this way requires less work to move a box from the ground to a loading dock than lifting the box straight up.
What is using a ramp?
300
For work to be done on an object that receives an upward force, the object must move this direction.
What is upward?
300
This is the unbalanced force that causes a book sliding across a horizontal tabletop to slow down.
What is friction?
300
This is the type of energy in heat.
What is thermal?
400
Use this to measure mass.
What is a triple beam balance?
400
You would have to use more force on this kind of ramp.
What is a short ramp?
400
This applied to an object causes movement.
What is force?
400
A sheet of notebook paper lying on a table remains motionless.
What are the results of balanced forces of gravity and a table on a piece of paper?
400
All of the following are examples of this: reading a science book, dropping a science book and holding a science book.
What is no work?
500
Using a graduated cylinder and a thermometer would allow you to measure these while wearing safety goggles.
What is volume and temperature?
500
These objects reduce force needed to raise objects.
What are inclined planes?
500
Batter walks to home plate with his bat; batter swings his bat; bat makes contact with the ball are all examples of this.
What is work?
500
To calculate work done, you must know both distance and this.
What is force?
500
An object remains stationary.
