In a distance/time graph, a straight line with a positive slope means the object is doing this.
What is going constant speed away from origin?
A student wants to know if more mentos would make his diet coke spray farther. In this experiment this is the IV.
What is number of mentos?
An object at rest, ...
What is remain at rest unless acted on by an unbalanced force.
If multiple forces act on an object it will move in this direction.
What is the direction of the greater force?
These are the three parts of a basic electromagnet.
What are a battery, a wire coil, and an iron core?
In a distance/time graph a curve trending upward means the object is doing this.
What is accelerating away?
A student wants to know if more mentos would make his diet coke spray farther. In this experiment this is the DV.
What is the distance the diet coke shoots?
An object in motion, ...
What is continue in the same direction and with the same velocity unless acted upon by an unbalanced force?
There's 10 N of force to the right and 20 N of force to the left. Calculate net force.
What is 10 N left?
What is they all have a magnetic field and two poles?
In a velocity/time graph, a horizontal line above the x-axis means the object is doing this.
What is going constant velocity?
A student wants to know if more mentos would make his diet coke spray farther. In this experiment this is something that should be held constant.
Answers may vary, but should mention temperature, brand of soda, how they're dropped in, etc.
This Newton's Law is why it's a good idea to wear your seatbelt.
What is First Law?
If the net force on an object is 0N, this is what it will do.
What is remain stationary?
To strengthen the power of an electromagnet, use _____ current, _______ loops of wire, and __________ voltage.
What are DC, more, and higher?
In a velocity/time graph, a line with positive slope means the object is doing this.
What is accelerating/speeding up?
In an experiment to see if adding salt would make water boil faster, this would be the DV.
What is time to boil?
This law is best summarized with the symbols F=ma.
What is second law?
This is the result of unbalanced, non-zero net force.
What is acceleration in the direction of the greater force?
This is how electric motors and electric generators are opposites.
What is motors use electricity and result in motion, and generators use the motion (of magnets inside wire coils) to create electricity.
In a velocity/time graph, a flat horizontal line on the x-axis means the object is doing this.
What is not moving?
In the experiment about adding salt to water to see if it would boil faster, this would be a control group.
What is a pot with no salt, just water in it?
