Vectors
100
This law states an object at rest tends to stay at rest. An object in motion tends to stay in motion.
The Law of inertia (Newtons First Law)?
100
These two quantities are the main relationship described by Newton's 2nd Law.
Force and Acceleration
100
What is Newton's third law?
Every action has an equal and opposite reation
100
A state of balance with no net force.
Equilibrium
100
An arrow that has both magnitude and direction is called this.
Force vector
200
This is the combination of all forces acting on an object.
Net force
200
This is the formula for acceleration that includes force and mass.
acceleration equals force divided by mass( a = F/m )
200
Actions and reactions can cancel out. This is true or false.
True!

If you drop a smooth, spherical 0.01kg marble and a 10 kg bowling off of the Empire State Building at the same time, this one will hit first.
The object that takes longer for air drag (friction) to equal the force of gravity, the bowling ball?
200
If you're hanging from both of your arms and your body is at equilibrium, then this is the sum of each arms' tensions.
What is your weight?
300
This is the SI Unit of Force.
Newtons
300
This is how to solve for m(mass) through Newton's Second Law.
mass equals force divided by acceleration m = F/a

The reaction of a rocket moving through space is that the gas from the rocket pushes it forward. This is considered initial action in this action pair.
Gas pushing on the rocket
300
One kilogram weighs this much in Newtons.
9.8 N
300
If two parallel ropes are holding up a 10 N load, this is the force each rope is exerting.
What is 5 Newtons?
400
Costas is playing freeze tag and is currently frozen. This is his net force (Fnet) and this is the name of that state he is in.
A net force of 0 and a state of equilibrium
400
Free fall is...
when an object that is only affected by gravity and no other forces
400
If an object of 80kg has a net force of 20N applied to it, this is its acceleration.
0.25 m/s2
400
If you run into the wall, it will hit you back with this.
An equal and opposite force. Ouch!
400
This happens when the angle of a rope in a vector increases.
What is the tension on each rope increases?
500
A 1kg book is on a table and is affected by gravity. A force is pushing up on the book to keep it from falling through the table. This is the amount of force and the name of the force.
Normal force of 9.8
500
When an object is falling off a high platform, what is the equal force of the object's weight?
Air resistance
500
We know the Earth pulls on the moon, and the moon also does this to the Earth.
What is the moon pulls on Earth with an equal and opposite force?
500
A huge oil tanker is NOT normally pushed off course by the waves or wind in the ocean because of this.
The ship has an immense inertia?
500
True or false. It is safer to hang from a horizontal rope (like a clothes drying line) than a vertical rope (like in PE class.
What is False?
