This unit is named after the English Scientist Issac Newton
What is the Newton?
100
The force that two surfaces exert on each other when they rub against each other.
What is Friction
100
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is Newton's First law?
100
For every action, there is an equal and opposite reaction.
What is Newton's third law?
100
Any object that orbits another object in space.
What is a satellite?
200
A small lemon.
What can be lifted up by one Newton?
200
How hard the surfaces are and what type of surfaces they are.
What are the two factors that friction depends on?
200
Galileo's concept of the resistance to a change in motion.
What is inertia?
200
"quantity of motion"
What is what Newton called momentum?
200
Any force that causes an object to move in a circular path.
What is Centripetal Force?
300
The combination of all forces acting on an object.
What is net force?
300
Occur when two solid surfaces slide over each other.
What is sliding friction?
300
acceleration = net force/mass
What is Newton's Second law?
300
Mass * Velocity
What is the equation to calculate momentum?
300
400 km
What is the height a space shuttle can reach?
400
A push or pull.
What is a force?
400
Mass and distance.
What are the two factors that affect gravitational attraction?
400
kg * m/s^2
What is the measurement of force?
400
In the absence of outside forces, the total momentum of objects that interact does not change.
What is the law of conservation of momentum?
400
7,900 m/s
What is the speed at which an object must be thrown in order to orbit the Earth?
500
When two unbalanced forces act in opposite directions.
What are unbalanced forces?
500
The friction that acts on objects that are not moving.
What is static friction?
500
The late 1600s.
What is the time period when Newton proposed his three laws of motion?
500
A force that pulls objects together.
What is gravity?
500
35,800 km
What is the height at which Communications Satellites are found?
