Newton's Laws
Mystery!
100
This is the unit we use for forces.
What is a newton?
100
This planet has more gravity than the other seven in our solar system.
What is Jupiter?
100
This type of friction is called traction on a car.
What is rolling friction?
100
This is the law that says "Every action force has an equal and opposite reaction force."
What is Newton's Third Law
100
This won't change about you no matter where you are in the universe.
What is mass?
200
This is the total force on an object, the sum of all the forces.
What is the net force?
200
The force on our bodies or other objects caused by gravity.
What is weight?
200
This type of friction makes objects stay in one spot.
What is static friction?
200
This law says objects stay in rest or in motion unless acted on by a force. Also called the law of intertia.
What is Newton's First Law?
200
This force allows you to stop your car before you hit something.
What is friction?
300
A force that draws all matter toward each other, an attractive force.
What is gravity?
300
This has a weaker gravitational strength than Earth and isn't a planet.
What is the Moon?
300
This type of friction forces objects moving against other objects to slow down.
What is sliding friction?
300
This law relates force, mass and acceleration into: F = ma
What is Newton's Second Law?
300
This force keeps your shoe laces tied.
What is friction?
400
These forces on an object will change the way the object moves.
What are unbalanced forces?
400
This is the strength of gravity on Earth.
What is 9.8m/s/s?
400
When friction occurs, this is created on the surfaces that rub together.
What is heat?
400
This law would explain why you are launched from a car if you don't wear a seatbelt.
What is the first law, intertia?
400
This fell on Newton when he was trying to figure out what caused gravity.
What is an apple?
500
When all forces on an object add up to 0.
What is a balanced force?
500
Gravity gets stronger between objects with more mass and weaker between objects with more of this.
What is distance?
500
These small areas of contact between two surfaces cause friction.
What are microwelds?
500
Newton did his work during this century.
What is the 17th century?
500
Bill Nye says this is a property of matter.
