Lessons from Hess
Name one thing you learned in Science class from 6th, 7th, or 8th grade.
As long as what you said is true, you get the points!
This is the direction that gravity always pulls things.
Down (or towards the Earth)
This is the universal force keeping you in your seat! Or at least it should be.
Gravity
One of these is NOT a form of energy.
Kinetic Energy, Distance Energy, Electrical Energy
Distance Energy
The best way to get something you need from Mr. K.
Raise your hand and ask for it.
List any one of Newton's three laws.
Double points if you get all three!
1: Objects in motion stay in motion, and objects at rest stay at rest, until a force acts on them.
2: Force = Mass x Acceleration
3: Every force has an equal and opposite reaction.
A runner sprints through the 100-meter-dash in 10 seconds. How fast did they go?
10 meters per second
(Speed = Distance/Time)
What would happen to a ball in motion, with no forces acting on it?
It will keep going forever until a force acts upon it.
The type of energy for heat.
Thermal Energy
When are you allowed to ask to use the bathroom?
At least 10 minutes after the start of class and 10 minutes before the end.
If you push a chair with 10N of force, how hard does the chair push back on you?
10N back on you.
Which is longer? 1000 centimeters or 1 meter?
1000 centimeters
(100cm = 1m)
This is the best way to make a stronger Impact without changing the Force.
Decreasing the Impact time (or making the Impact faster/sharper)
Kinetic Energy
The only two people who are allowed to help you on a quiz.
Mr. K and Mr. John.
What is the difference between a Thermal Conductor and a Resistor?
A Conductor transfers heat quickly where a Resistor transfers heat slowly.
This is the property of speeding up or slowing down.
Acceleration
The four types of friction, 100 points for each you can name.
Static Friction, Sliding Friction, Rolling Friction, and Fluid Friction.
A rock with 1000J of Gravitational Potential Energy falls off a cliff. Right before it hits the ground, this is how much Kinetic Energy it has.
1000J
When are you allowed to throw things in Physics class?
When we have a lab that requires throwing something.
The process of warm air rising and pushing the cold air down.
Convection
A car drives at 60mph for 5 minutes, how far will it have gone?
5 miles
If you want to get a 5kg ball rolling at 10 m/s^2, then you'll need to use this much force.
Do the math!
A. 25N B. 15N C. 50N D. 100N
50N
(Force = Mass x Acceleration!)
A 100kg man is standing on a 10m balcony. How much Gravitational Potential Energy does he have?
A. 9J B. 1000J C. 110J D. 9,800J
9,800J
(Force of Gravity = Mass x 9.8)
(Gravitational Potential = Force x Height)
Ask Ms. Nia.
Did that count for points?
