What is the definition of a force?
The result of two objects interacting.
100
Friction depends on these two things.
What is surface type and weight?
100
This is the property described by Newton's first law that every object has.
What is Inertia?
100
What type of force propels a car or bike forwards (between the wheels and road)
friction

What happened one week from today (April 15) in 1912?
The titanic sank
200
These are the two general types of forces
What is contact and field?
200
the force due to gravity is commonly known as _____
What is weight?
200
Newton's third law states that ___________.
What is forces come in pairs (and they are equal and opposite?)
200
what does this symbol mean: ∑
"net" or "sum of"
200
Before Mike Myers got the role, which actor voiced almost all of the lines for the Shrek character before his death in 1997?
Chris Farley
300
Forces cause an object to do this.
What is acceleration?
300
This man's law describes the force from a stretched spring. Bonus for first name!
Who is Robert Hooke?
300
According to Newton's second law, if you drop objects (down a stairwell for example) as you increase the mass of the objects dropped and the acceleration towards the ground doesn't change, what must have been happening to the force as the mass was increased?
It must have been increasing as well. (F=ma)
300
name three field forces
Gravity, magnetic, electric
300
What Olympic sprinter is currently on trial for murder?
Oscar Pistorius
400
Forces can balance each other out because they have both magnitude and this.
What is direction?
400
As described by Hooke's Law, the two quantities that are proportional when a spring is stretched are ______and ________.
What is Force and distance stretched?
400
Why aren't the two equal and opposite forces acting on a rope in an even tug of war battle an example of a Newton's third Law pair of forces?
Because they are both acting on the same object.
400
What is the newton's third law pair for the situation where the force of gravity pulls down on a table?
The table pulls the earth up with an equal gravitational force.
400
Before UCONN won four in the last 15 years, which school was the only school from New England to win an NCAA men's basketball championship?
HOLY CROSS!!
500
True or false? to keep and object in motion there must be some force acting on the object.
What is false?
500
This is the proportionality constant in the friction force equation. It describes how well two surfaces slide against each other.
What is the coefficient of friction?
500
Why don't rockets need anything to push against? (use Newton's third law in explanation)
Because when a rocket pushes its propellant (which has mass) downwards, the mass pushes back with an equal and opposite force pushing it up
500
In the A-team clip, when the tank begins to fall without parachutes, how come the people in the tank begin to float around in the tank?
because every object falls at the same rate
500
Before CD's and DVD's there was a technology that combined the size of a vinyl with the laser technology of CD's and DVD's. What was this hybrid disc called?
LaserDisk
