Newtons 1st
Newtons 1st law is also known as this
what is law of inertia
Formula associated with Newtons 2nd law
What is F= mass x velocity
Newtons 3rd law states
For every action there is an equal and opposite reaction
An educated guess
hypothesis
What does m/s/s represent?
acceleration
an object in motion will do this
What is continue in motion till acted on by an outside force
The product of F = mass x velocity
What is net force
What are two forces that interact with each other called
action and reaction forces.
The first step of the scientific method
ask a question
What does kg represent?
mass
This determines the amount of inertia an object has
What is the Mass
The unit of force is what?
What is newton
Rocket exhaust pushes down on the Earth and results in what
The rocket goes into the air
the information gathered during an experiment
measurements
What is the force on a 2000 kg elevator that is falling freely at 10 m/s/s
20000 Newtons
Will Cause an object to move
What is unbalanced forces
The second law of motion explains what about falling objects
objects hit the ground at the same time
The more action an object sends in one direction
The more the reaction in an opposite direction
In an experiment, the group that serves as the standard for comparison.
control group
An object accelerates 3.0 m/s/s when a force of 20.0 newtons is applied to it.
What is the mass of the object?
6.67 kg
A force that acts on objects to change their motion.
What is friction
What acceleration will result when a 12 N net force applied to a 3 kg object?
What is 4 m/s/s
Gravity, electricity, magnetism are forces. what is the other type of force?
friction
in an experiment the factor that is changed by the tester
independent variable
An object with a mass of 1500 g (grams) accelerates 20.0 m/s2 when an unknown force is applied to it. What is the amount of the force?
30000 newtons
