Newton's 1st law
Define Newton's first law
An object will in motion, or at rest, unless acted upon by an outside force
Define both 2nd and 3rd law
2nd: The acceleration of an object depends on the mass and force
3rd: Every action has an equal and opposite reaction
Define kinetic and potential energy
Kinetic: Energy when an object is in motion
Potential: The energy an object potentially has due to position and mass
What are the three variables that make up newtons 2nd law?
Force
Mass
Acceleration
No
Name the four types of friction
Rolling
Sliding
Fluid
Static
Solve this equation: What is the force of an object that has a mass of 22 kg and accelerating at 14 m/s/s?
308 N
Solve this question. A 8,000 pound elephant is laying on the ground. What is the GPE?
Zero- there is no height because the animal is not off the ground
Which Newton's law is this?
-I am trying to jump as high as I can. I push really hard into the ground to jump high.
3rd law
What time periods did Mr. Blader want to go back to?
Ancient Egypt
Revolutionary War
If I weigh 200 pounds on earth and go to another planet that has twice the gravity as earth. How much would I weigh on that planet?
400 pounds
What relationship does mass and force have with acceleration?
Mass: Inverse relationship
Force: Direct relationship
Solve the equation. A person is running at a speed of 20 m/s and produced 147 Joules of energy. What is the mass? (round to hundredths place)
.74 Kg
What are the labels for ke=mv^2 and GPE=ham?
ke= J m= kg v= m/s
GPE= J h= meters a= m/s/s m= kg

Blue whale
Which object has the least amount of inertia?
1,000 pound lion
4,000 pound lambo
2,000 pound elephant
Solve. Mass is 47 Kg and Force is 543 N. What is the acceleration? (round to nearest tenth)
11.6 m/s/s
An object fell 46 meters and produced 7,987 J of energy. What was the mass?
17.72 Kg
Possible answers:
Create a rougher surface
Increase the mass of the object
Increase the surface area
What is the last planet in our solar system?
Neptune
Which object is experiencing the least amount of friction?
a 1000 pound box sliding on ice
a 300 pound box sliding on ice
Which object will have a greater acceleration? No math
Object 1- force: 40 N Mass: 33 Kg
Object 2- Force: 62 N Mass: 33 Kg
Object two
What is the velocity of an object that has a mass of 77 kg and produces 2,476 J of force. (round to nearest hundredths)
8 m/s
Which object will have the least gravitational potential energy?
A ball falling from 36 meters that weighs 23 kg vs a ball falling from 33 meters and weighs 23 kg
Least: the one falling from 33 meters
