Which produces the greater change in kinetic energy exerting a 10-n force for a distanceof 5m or exerting a 20-n force over a distance of 2m?

Strictly this should be done in terms of line integrals but for a constant force the result simplifies to
change in KE = Force * distance
so 10N over 5m changes KE by 50J and 20N over 2m changes KE by 40J.

What is greater distance or displacement?
Distance is greater , because displacement can be zero ,but, distance cannot be zero.
Does friction affect stopping distance?
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
Gravitational force to distance and mass?
The greater the mass the more gravitational force an object has, the greater distance, say from the ground the greater potential energy, the greater gravitational force. hope that helps :]
When leaving earth how do you overcome gravity?
You do it by exerting a force greater than the gravitational force, in the opposite direction ... a lot like what you do with your legs when you want to climb some stairs.
Is the equation that shows distance varying inversely with time true?
greater distance takes greater time. it is not an inverse operation, they have a positive correlation.
Two factors that influence the pull of gravity?
The mass of the object exerting the gravitational pull, and the distance between the two objects. Gravity is all over, but it's effect varies greatly with distance. The girl next to you in Science class is actually exerting a greater gravitational pull on your mass than the Sun, despite their obvious differences in size.
How does a jack make changing tires easier?
By using leverage, it allows you to lift a 1 or 2 ton car. Have you tried lifting a car by hand without a jack? And you DO need to lift the car to change a tire.
Which has a faster air pressure fall between a hurricane or tornado?
A tornado produces a greater pressure drop over a shorter distance than a hurricane.
What is greater distance or displacement?
Distance is greater , because displacement can be zero ,but, distance cannot be zero.
Is it a greater distance from Memphis to Chicago or from Albuquerque to Billings?
Albuquerque to Billings has a greater distance.
Which distance is greater the distance between the North and South poles or the distance around the Tropic of Capricorn?

Which distance is greater 0.7 or .10 of a mile?
.7 is a greater distance by 6/10 of a mile.
Which distance is greater Chicago to new Orleans or Chicago to Maine?
Chicago to Maine is a greater distance
Are speed and distance directly proportional or inversely proportional?
Directly proportional. Greater speed - greater distance.
What distance is greater; Chicago to New Orleans, or Chicago to Augusta, Maine?
The greater distance is Chicago to Augusta
Does friction affect stopping distance?
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
Which is greater 1mm or 1 km?
1Km is the greater distance !
