Name the four fundamental forces in creation. Which two forces are really different aspects of the same force?
Gravitational force electromagnetic force week force strong force
Which is the weakest force of the fundamental forces? Which is strongest?
The gravitational force is the weakest the strong force is of course the strongest
Name the first of the three principles of newtons universal law of gravitation
One. All objects mass are attracted to one another by the gravitational force
Name the second principle of newtons law of gravitation
Two. The gravitational force between two masses is directly pro for Chanel proportional to the square of the distance between the two objects
Name the third principle of newtons universal law of gravitation
The gravitational force between two masses is invert in Lee proportional to the square of the distance between those two objects
The gravitational force between two objects Nas one equal 10 KG, mass to equal six KG is measured when the objects are 10 cm apart if the 10 KG masters or pastry with a 20 KG Mas in the 6KG Mas is replaced with the 12 KJ mask what how does the new gravitational force compared to the first one that was measured
2×2 is 4
4 times
The gravitational force between two objects mass one equal 10 KG, mass to equal six KG is measured when the objects are 10 cm apart if the distance between them is an increased to 40 cm how does the new gravitational attraction compared to the first one that was measured
10 . 4 = 40
So G divided by four squared equal?
16 times smaller
The gravitational force between two objects mass one equals one negative G, Nas two equal to negative KG is measured win the objects at 12 seven nearest park if the one KG NASA replaced was the five-KG Nas the two KG mass it is replaced of the four KG mass and the distance between the objects is reduced to 4 cm how does the gravitational force compared to the first one that was measured?
1×5 = 5, 2×2 = 4,
5×2×9 = 90 Timesbigger
Is Venus orbits the sun because of the fans exert a gravitational force on it what is the equal and opposite force required by noon third law of motion?
Venus
What kind of force is necessary for a circular motion? Give the definition of that force
Centripetal force: The force necessary to make an object moves in a circle. It is directed perpendicular to the velocity of the object which means it. Towards the center of the circle points towards the center of the circle
What is the first of the three principles of circular motion
One circular motion require centripetal force
Taylor what is the second principle of circular motion?
Two. The larger the centripetal force the faster the object goes in a given circle size
What is the third printable a circular motion
Any given speed, the larger force will make in the circle smaller
And Olympian event is called a hammer throw an athlete twirls iMessage ball on the end of a wire. Once he gets the ball twirling very quickly the athlete releases the wire allowing the ball to fly straight out into the field the person throws the ball the farthest away is the winner
A. As the athlete trust them off faster and faster the wire will play more or less or about the same amount of sibling trip at all fours.
B. Supposed the athlete starts by grouping the wire close to the balls to the wall sweep it out a small circle then keep passing the ball and a consistent yellow someone the way I just looked it into the boss leaves out larger in Rogers Circle will the Wyler wire exert more or less RC mountain force
More
B. Less
What is centrifugal force
There is no such thing
