Newton's law
100
An objects change in position
what is motion?
100
a push or pull exerted on an object to change the motion of an object
What is force?
100
a force that opposes motion between two surfaces that are in contact
What is friction?
100
A force of attraction between objects that is due to their masses.
What is gravity?
100
this describes the relationship between gravitational force, mass, and distance
What is Newton's law?
200
an equation to measure speed
What is total distance divided by total time?
200
the SI unit for force, symbol-N
What are Newtons?
200
this is the friction between moving surfaces
What is kinetic friction?
200
as the distance increases between objects, this happens to gravity
What is a decrease in gravitational pull?
200
one question about Earth Isaac Newton used to create Newton's law
What is "Why do objects fall toward Earth?"
300
the acceleration that occurs in a circular motion
What is centripetal acceleration?
300
the combination of all of the forces acting on an object
What is net force?
300
a force that is applied to an object but does not cause the object to move
What is static friction?
300
gravity is applied based on this
What is mass?
300
another question about the solar system that Isaac Newton used to create Newton's Law
What is "What keeps the planets moving in the sky?"
400
this is how an object can accelerate
What is changing speed, direction, or both?
400
this type of force produces no change in motion
What is balanced force?
400
the factors that effect friction
What are the roughness of surfaces and the amount of force pushing them together?
400
gravity impacts this measurement
What is weight?
400
what are all objects in the universe attracting each other through gravitational force.
What is the law of universal gravitation?
500
the speed of an object in a particular direction.
What is Velocity?
500
this is a force that produces a change in motion
What is unbalanced force?
500
to reduce friction, apply this substance
What are lubricants?
500
Earth's gravitational pull does this
What are all the objects on earth being pulled to the center?
500
This is how Isaac Newton concluded Newton's Law.
What is Isaac Newton's watching an apple fall from a tree?
