Newton's 1st Law
If an object has 10N of force upwards, and 10N of force downwards then it is...
is Balanced or not going to move
What is the formula to calculate newtons second law?
F= m * a
Define an action.
The process of doing something.
Forces that DO NOT cancel each other out
What is Unbalanced forces
The sum/total of forces acted upon an object
What is net force?
What is the amount of matter an object takes up?
Mass
when an object speeds up slows down or changes direction.
What is acceleration?
What is a collision?
When moving object or person strikes or collides violently against another.
What is a dependent variable?
The variable that is being measured in the experiment.
If you were trying to move a 10lb chair versus a 100lb refrigerator. Which object would have the most inertia? and why?
The 100lb refrigerator because it has the greatest mass which also means more force is needed to move it and more inertia.
In american football, when is newtons 2nd law of motion used?
Kicking a football
What is force measured in?
Newtons (N)
What is the action and reaction with a person hiking up a mountain.
Action: The person's foot applying force onto the ground.
Reaction: The ground pushing back up on the person's feet
What is an independent variable?
The variable that is manipulated or changed in the experiment.
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)
A trash can of heavy materials needs to be moved. The trash man Arnold starts to pull the trash can with 100 N of force and the other guy Roger, pushes the trash can to Arnold with 25 N of force. What is the net force?
Net Force: 125 N of Force
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.
What is Newton's first law word for word
WITHOUT LOOKING AT NOTES
An object in motion tends to stay in motion, and an object at rest tends to stay at rest unless acted upon by an unbalanced force.
An object with a mass of 10 kg is pushed with a force of 20 N, what is the acceleration?
a = 2 m/s2
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
What is Newton's 3rd Law? word for word
WITHOUT LOOKING AT NOTES
For every action (force), there is an equal and opposite reaction (force).
If you know a 100kg car traveled 300 m/s2, you can find its __________. And what is the answer?
Blank: Force
Answer: 30,000N
