What is the definition of inertia?
the resistance an object has to a change in its state of motion.
100
Acceleration is :
the rate at which velocity/speed changed. ( speeds up )

Fill in the blank If an object is at ____, then there are no forces acting upon the object.
Rest

true or false ; Mass And density are the same thing !
False , Mass is the measure of the amount of "stuff" in something density is how much of the object is packed into a certain amount of volume.

Is gravity a force?
Yes

How do you make objects accelerate?
You must apply a force.

Mike's car, which weighs 1,000 kg, is out of gas. Mike is trying to push the car to a gas station, and he makes the car go 0.05 m/s/s. This is an example of which law .
Newtons second law of motion
200
True or false ; The mass of an object can be measured in pounds
false

What is gravity?
Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles.
300
True or False : Inertia is a force .
false

True or false ; Your riding a bike at a constant speed That is acceleration.
False , The only way it would be accelerating is if an unbalanced force it acted upon it , and cause it to go faster .
300
It would take a(n) _______ force to keep an object in motion at a constant velocity.
unbalanced
300
Are weight & Mass the same thing?
Yes
300
Which of these is the correct formula for gravity ? F= a x m , F=Gm1m2 / r2, a=f/m
F=Gm1m2 / r2,
400
Could we survive with out inertia?
No. If there wasn't any inertia the world would come to a complete stop, and there would be no Earth.
400
What is the formula for measuring acceleration?
a=F/m
400
True or false ; Newton's first law of motion is applicable to both moving and non-moving objects.
True - Absolutely true. Like all true scientific laws, they govern all objects. In the case of Newton's first law of motion: An object that is nonmoving remains at rest (unless acted upon by an unbalanced force); and a moving object will continue in its motion at a constant velocity (unless acted upon by an unbalanced force).
400
true of false :The mass of an object is dependent upon the value of the acceleration of gravity
False - Mass is independent of the gravitational environment that an object is in and dependent solely upon the number of atoms in the object and the type of atoms

If you throw a basket ball in the air and it fall right back to the ground this is an example of :
Gravity being exerted
500
True or false ; Mass And Inertia are the Same thing
No , They are close, but not the same thing.
500
What is the difference between acceleration And Deceleration?
Acceleration : Increase in the rate or speed of something. The rate of change of velocity per unit of time. Deceleration : a decrease in rate of change. Basicly Acceleration means speeds up & deceleration means slow down.
500
Which Law is this ; An object at rest will stay at rest, forever, as long as nothing pushes or pulls on it. An object in motion will stay in motion, traveling in a straight line, forever, until something pushes or pulls on it.
Newton's first law of motion
500
The standard metric unit of mass is the _____
kilogram
500
how does gravity affect acceleration?
Gravity, or any force, causes an object to accelerate, that is, it moves faster and faster in the direction of the force.
