Moving within the Law
The law that states that an object at rest wants to stay at rest.
What is the 1st Law of Motion?
The force that pulls objects toward the center of the earth,
What is gravity?
A force that holds back the movement of an object.
What is friction?
Friction that slows things down in air or water.
What is drag?
The law of inertia.
What is the 1st law?
Tthe force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
What is centripetal force?
A substance that reduced friction.
What is a lubricant?
An object that is shaped in a way that allows it to travel through the air or water more easily.
What is aerodynamic?
The law that states that for every action there is an equal and opposite reaction.
What is the 3rd Law of Motion?
Scientist who described the laws of gravity and motion.
Who is Sir Issac Newton?
When something sticks to something else.
What is adhesion?
DOUBLE JEOPARDY!
Give two examples of jobs that require friction to be accomplished successfully.
The law of acceleration.
What is the 2nd law?
The speed limit for falling.
What is terminal velocity?
Occurs when material sticks to itself.
What is cohesion?
DOUBLE JEOPARDY!
Give a TWO examples of lubricants.
What are oil, soap, water?
The law that states that force is needed to change direction (acceleration) and that that force changes dependent on the mass of the object.
What is the 2nd Law of Motion?
Explain Galileo's Cannonball Experiment and what he proved.
He dropped two different sized cannonballs from the top of a tower. They both hit the ground at the same time, proving that objects fall at the same rate, regardless of mass.
The friction between two objects that keeps them from sliding across each other
What is traction?
A push or a pull that changes an object’s state of rest or motion.
What is a force?
