This law states an object at rest tends to stay at rest. An object in motion tends to stay in motion.
What is The Law of inertia (Newtons First Law)?
These two quantities are the main relationship described by Newton's 2nd Law.
What are Force and Acceleration?
What is Newton's third law?
What is-Every actioin has an equal and opposite reation?
A state of balance with no net force.
What is equilibrium?
An arrow that has both magnitude and direction is called this.
What is a force vector?
This is the formula for acceleration that includes force and mass.
What is acceleration equals force divided by mass?( a = F/m )
Actions and reactions can cancel out. This is true or false.
What is 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.
What is the object that takes longer for air drag (friction) to equal the force of gravity, the bowling ball?
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?
This is how to solve for m(mass) through Newton's Second Law.
What is 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.
What is the gas pushing on the rocket?
One kilogram weighs this much in Newtons.
What is 9.8 N?
If two parallel ropes are holding up a 10 N load, this is the force each rope is exerting.
What is 5 Newtons?
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.
What is a net force of 0 and a state of equilibrium?
Free fall is...
What is an object that is only affected by gravity and no other forces?
If an object of 80kg has a net force of 20N applied to it, this is its acceleration.
What is 0.25 m/s2?
If you run into the wall, it will hit you back with this.
What is and equal and opposite force? Ouch!
This happens when the angle of a rope in a vector increases.
What is the tension on each rope increases?
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.
What is the Normal force of 9.8?
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?
A huge oil tanker is NOT normally pushed off course by the waves or wind in the ocean because of this.
What is the ship has an immense inertia?
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?
