A push or pull
What is a force?
100
The force that occurs when two surfaces exert on each other when they rub against each other.
What is friction?
100
Inertia depends on this.
What is mass?
100
A characteristic of a moving object that is related to the mass and velocity of the object.
What is momentum?
100
Objects that orbit other objects in space.
What are satellites?
200
How strength of force is measured.
What is a newton (N)?
200
An example of this is trying to move a couch that will just not budge!
What is static friction?
200
An example of this is when you walk, you push backward on the ground with your feet.
What is an action-reaction pair?
200
The equation for finding momentum.
What is mass x velocity?
200
Daily Double! Lesson 5 might make you think of this famous Tom Petty song.
What is "Free Falling?"
300
The sport that was the subject of lesson 1 MPD.
What is soccer?
300
Sidewalks become slippery when it rains because of this.
What is fluid friction?
300
An alternate name for Newton's first law of motion.
What is the law of inertia?
300
The subject of the Lesson 4 MPD.
What is air hockey science?
300
What GPS stands for.
What is Global Positioning System?
400
This is what happens when forces act in the same direction.
What are added strengths?
400
This states that the force of gravity acts between all objects in the universe that have mass.
What is the law of universal gravitation?
400
The equation to determine acceleration.
What is acceleration = net force/mass?
400
The law of conservation of momentum states that total momentum of objects that interact does not change in the absence of this.
What are outside forces?
400
Newer satellites have an expected lifespan of this many years.
What is 7-8?
500
What forces cause.
What is ALL changes in motion?
500
The subject of the lesson 2 MPD.
What are Space Athletes?
500
The book published by Newton in the 1680's that set down his laws of motion.
What is Mathematical Principals of Natural Philosophy?
500
The word momentum comes from this Latin word, meaning "to move."
What is movere?
500
A picture of this sport was shown in Lesson 5 to demonstrate centripetal force.
