Friction and Gravity
T or F: Gravity is a force
True
Draw an atom (Don't have to label and you don't have to be Van Gogh)
If it's close enough, you get the points
Sir Issac Newton
Is force needed to change motion, yes or no?
Who is cooler, Charles or Araceli?
Charles (or Araceli)
T or F: Friction is a force
True
Is a Proton positive, negative, or neutral charge?
Positive
What is a unit of force called?
Newton
Do moving moving objects have energy, yes or no?
Yes
Does friction cause heat?
Yes, movement causes heat/thermal energy
Does friction cause objects to go slower or faster or it depends?
It causes things to go slower. You want to decrease friction to go faster. An increase in friction causes you to go slower
Is a Electrons positive, negative, or neutral charge?
Negative
What is the first law of motion?
An object at rest will stay at rest in a straight line unless a force is acted upon it
If I am riding my board and I hit a pebble do I
A. Fall forwards
B. Fall backwards
C. Keep Riding because pebbles do nothing to stop boards (Don't pick C)
When I am riding the board, I am going forwards on the board. But the pebble causes a force going in the opposite direction of the board. So the board has an opposing force acting on it and it stops. But I am still going forwards and the pebble doesn't act on me so I fall.
Which Queen member is a astrophysicist and looks like Issac Newton?
A. Brain May
B. Freddie Mercury
C. Roger Taylor
D. John Deacon
Brian May (Points will not be taken off)
Which will reach the ground first if I am dropping it from a building, a heavy bowling ball or a small baseball?
Trick question: The two objects will reach the ground at the same time. :)
Is everything in the universe made of atoms?
No, energy isn't made up of atoms
What is the second law of motion?
An object that has an unbalanced force acting on it will accelerate in the direction of that force.
The greater of the mass of the object the more force you will have to use to make it accelerate.
No, energy cannot be created or destroyed. It could move into another object and change form.
What supposedly fell on Newtons head?
An apple
Gravity affects things with blank
Mass
What is the group of protons and neutrons in the center called?
Nucleus
What is the third law of motion?
Forces always occur in equal and opposite pairs.
Basically when you put force on an object, the object will exert an equal amount of force in the opposite direction. If you push on a wall behind you while on a board, the wall will push back making you go forward.
Define Kinetic and Potential Energy
Kinetic: Energy of motion, something that is moving or releasing energy
Potential Energy: Energy being withheld, stored energy
What happens when you split an atom?
(Fine if you don't know, points will not be taken off for this question)
An nuclear explosion
