Gravity on a plane is less then on a hill because you are away from the earth, However gravity in a plane over a hill is more then gravity on a plane over a valley at the same altitude above sea level.
Lift generated by the wings of a plane counteracts the force of gravity pulling it down, allowing the plane to stay in the air. For a plane to achieve lift greater than gravity, it must generate enough thrust through its engines to maintain forward motion and generate sufficient lift from its wings to overcome the force of gravity.
Using a short inclined plane is generally easier than using a long not so steep inclined plane. A shorter inclined plane requires less force to move an object up the incline compared to a longer, less steep incline. The shorter distance also means less work is needed to overcome friction and gravity.
Rolling a wheel up a hill and riding a bike on a flat path are the examples that best describe using an inclined plane because they both involve overcoming gravity and requiring less force than lifting vertically. Unscrewing a lid from a jar and taking a trunk down from a shelf are not examples of using an inclined plane.
While, if the hill is 90 degrees, then it is a cliff. That is to say, that you are not receiving any "help" from the 90 degree hill. You are just lifting the object straight up. Whereas the 20 degree hill provides a ramp.
The specific gravity of a product is the ratio of its density to the density of water. It provides information about how dense the product is compared to water, which has a specific gravity of 1. Products with a specific gravity greater than 1 are denser than water, while those with a specific gravity less than 1 are less dense than water.
Yes, gravity is lower the further one is away from the centre of the Earth, so it is lower at the top of a hill than the bottom.
Gravity pulls it down and the weight of a car is less dense than a hill and therefore it goes down
The moon has less mass than does Mars and therefore has less gravity at its surface.
Yes, it is significantly less.
The moon has less mass than Earth. Gravity is proportional to mass, so there is less gravity on the moon.
Why does Mercury and Mars have less gravity than Earth because they both have less mass than does the Earth.
There is much less gravity on Mercury.
less
Gravity is the attraction between masses. And since the moon has less mass than earth, the gravity is weaker there. Over a distance gravity is weaker.
It doesn't. The moon has less gravity than Earth because it has less mass.

The "surface gravity" is less on Uranus.
