Newton
He developed a theory describing this?
Gravity
When baseball players hit the ball hard enough, their bats can sometimes break. What is exerting a force on the bat, causing it to break?
The ball
What is inertia?
The tendency of an object to resist changes in its velocity.
Another way that the gravitational force acts is to hold the planets and their moons in an orderly arrangement is called what?
Solar system
The Gravitational Force Between Objects is What?
Mutual
Newton's first law states that an object in motion (or at least rest) will tend to do what?
Stay in motion
List the outer planets
Jupiter, Saturn, Uranus, and Neptune
What is friction?
A force that results from surfaces rubbing against one another.
What is centripetal force?
The force necessary to make an object mice in a circle. It is directed perpendicular to the velocity of the object, which means it points toward the center of the circle.
The earth is held in its orbit around the sun because of what?
The sun's gravitational force attracts the earth to it.
Newton's first law states that an object will continue moving until when?
It is acted on by an outside force
Which planet in the solar system receives the least amount of isolation?
Neptune
What is total force?
(Mass) X (acceleration)
The region of the solar system where we find the highest concentration of asteroids.
Who proposed the General Theory of Relativity?
Albert Einstein
In Newton's Second Law, when an object is acted on by one or more onside forces, the total force is equal to what?
The mass of the object times the resulting acceleration
What part or parts of a comet come and go during a comet's orbit?
The coma and the tail
What is air resistance?
The friction experienced by objects traveling through the air.
Some scientist call these
"dirty snowballs".
comets
The other theory of gravity that says two massive objects tend to exchange tiny particles is called what?
Gravitons
What is Newton's Third Law?
For every action, there is an equal and opposite reaction.
What theory says that gravity is caused by the exchange of particles between objects with a mass?
The graviton theory
What is kinetic friction?
Friction that opposes motion once the motion is already started.
What is centripetal acceleration?
An object that is accelerating, even though its speed is not changing.
Which is the weakest of the fundamental forces?
The Gravitational Force
