Newton's First Law
What is Newton's First Law?
Newton's First Law states that an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by an external force. (This has to do with Inertia.)
What is Newton's Second Law?
The acceleration of an object is directly proportional to the magnitude of the force used, and the larger the mass of an object the more force it requires.
What is Newton's third law?
For every action, there is an equal and opposite reaction.
In the Forces of Motion simulation how did friction affect your objects in motion?
It slowed them down over time
Newton came up with the three laws of motions all by himself
False Many people throughout history had come up with some of them separately.
What is Inertia?
The effect that makes an object continue doing what it is already doing
What is the difference between acceleration and velocity?
Velocity is the speed of an object and acceleration is the change in speed of an object
In the balloon experiment how did the amount of air in the balloon impact the experiment?
The more air the further the balloon went (for the most part)
In the Impulse game, what happened to your sphere when you clicked closer to it?
You applied more force
Large objects and small objects have the same amount of Force on each other.
True
In the coin experiment why did more coins make the experiment easier?
The more mass an object has the more inertia it has.
For our Pinewood derby cars, why will more mass at the end of the car help make it go faster?
When the largest part of the car is further up there is more potential energy.
When we push up against the earth what happens to the earth?
We move the earth (so slightly you almost can't measure it)
In the Civiball Game why do larger balls have more force?
They have more mass
Inertia is a property of matter
True
In the coin experiment, what force was acting on the coins that made them fall into the cup?
Gravity
What is the difference between mass and weight?
Mass is how much matter an object contains and weight is the force of gravity on that objects mass.
Fill in the blank: In a situation where no other forces are acting on an object, the amount of ___________ energy possessed by an elevated object will be directly equal to its Kinetic energy.
Potential
In the TED ED video what happens to you when your bicycle tires touch the ground?
You are forced forward
Newton's laws only apply in our solar system
False
What two forces make us come to a relative stop?
Gravity and Friction
What is the equation for Newton's second law of motion?
Force=mass x acceleration
We measure mass in kilograms, what unit do (or should) we measure weight in?
Newtons
In one of the video series we watched on Newton's laws, name one sport was used to show how these laws worked?
Football or Golf
We are all currently in motion
True
