is Balanced or not going to move
What is the formula to calculate newtons second law?
F= m * a
What kind of force causes there to be no motion?
Balanced or Unbalanced force
Balanced force
What is an independent variable?
The variable that is manipulated or changed in the experiment.
An object with a mass of 10 kg is pushed with a force of 20 N, what is the acceleration?
a = 2 m/s2
What is the amount of matter an object takes up?
Mass
Fill in the Blank.
It requires __________force to push an empty box than one filled with books.
What is a dependent variable?
The variable that is being measured in the experiment.
Forces that cancel each other out
What is Balanced forces
In american football, when is newtons 2nd law of motion used?
Kicking a football
when an object speeds up slows down or changes direction.
What is acceleration?
Joe challenges you to a race with hurdles and your mass is 100kg. You are running at 5 m/s2 , What would be the amount of force you would hit if you tripped over the hurdles?
What equation would you use to solve the problem?
Bonus: 100pts for the correct answer
F = mxa
F = 100kg x 5 m/s2
F = 500 N
Name the difference between a Controlled variable and an Independent variable.
Independent: manipulated or changed in the experiment.
Controlled: Constant and assists with the accuracy of the results
What is the type of force that causes resistance and nearly everything to come to a stop?
Friction
What does m/s2 stand for?
meters per second squared
Name each of the units,
Force =
mass =
acceleration =
Force = Newtons (N)
mass = kilograms (kg)
acceleration = meters per second squared (m/s2)
What is force measured in?
Newtons (N)
In this study what is the "dependent variable"
Study: Are the test scores of students impacted by the amount of time spent sleeping the night before the test.
The test scores of the students.
Net force does not equal 0
Unbalance forces
If Amy is pushing a table with 20 N from the East side, and Joey is pulling the table with 20 N from the West, and Michelle is pushing the table from the North side with 50 N what would like drawing look like?
Show on board
Fill in the Blank for the explanation of Newton's 2nd Law of Motion
A __(larger or smaller)___ net force acting on an object causes a__(larger or smaller)___ acceleration, and objects with __(larger or smaller)___ mass require __(more or less)___ force to accelerate.
1st Blank: Larger
2nd Blank: Larger
3rd Blank: Larger
4th Blank: More
How does the mass of an object impact how much force needed to out on the object to move?
The greater the mass the more force needed to move the object.
