Newton's Laws
Newton's first law states that "For every action, there is a " what?
Equal and opposite reaction.
A quick, simple definition. What is a force?
A push or pull.
Which planet has the strongest gravitational force?
What is Jupiter?
What's speed with a direction called?
What is velocity?
What is the smallest planet (as of 2019)?
What is Mercury?
What are Newton's Laws?
Three laws, that lay down the foundations of motion/ Three laws stating the basics of motion, Three laws explaining motion, mostly anything along these lines.
Units used to measure force?
What are newtons?
What factors affect gravity?
(There are two)
Mass and distance.
I'm driving my car 60 miles per hour SW (South West). Is how fast I'm going measured in acceleration or velocity?
It's measured in velocity because you are moving, and it's in a direction.
What is the neighborhood where Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune orbit around the Sun called?
The Solar System.
Newton's second law states what?
Force equals mass times acceleration.
If there's a ball in a car, and the car abruptly stops, why does the ball roll forward?
Because of inertia.
As gravity changes, something else does as well. What?
Weight.
If you're turning in a circle, but moving at a constant speed, are you accelerating?
Yes, because you're changing direction.
It separates the two planets Mars and Jupiter and stretches all the way around the solar system.
What is the asteroid belt?
An object will remain in motion or rest until acted upon by what?
An external force/force. Either answer works here.
What is the sum of all forces acting upon an object called?
What is a net force?
What is the strength of gravity on earth?
9.8 meters/second?
What are the units used to measure acceleration?
What are meters per second squared?
What is beyond Neptune? This part of our solar system has Pluto and many other dwarf planets in it.
The Kuiper Belt.
Under Newton, F=ma. But under Aristotle, this is different. What is it?
F=mv
According to Aristotle, there is only a velocity if there is a force, but according to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause an acceleration (that is, a change in the velocity).
A unit of force that, acting on a mass of one gram, increases its velocity by one centimeter per second every second along the direction that it acts.
What is a dyne?
When something falls from a high altitude, gravity acts upon it. If we're on Earth, in the first second, it moves at 9.8 meters/second. How fast does it move in the next second?
19.6 meters per second.
What's the formula for acceleration? In other words, how do you calculate acceleration?
What is a=F/m?
A center of gravity that Pluto and one of its moons, Charon, orbit around.
What is a barycenter?
