They are afraid to embrace the power of the graph. OK, let's do a simple ... of the cart to something else---the local gravitational field. Here is a force diagram for a cart (with no friction ...

then the distance between the Earth and the Sun changes. If we kept the strength of gravity the same, and increased the mass of the Sun, the Sun would exert a stronger gravitational force on ...

Issac Newton's Law of Universal Gravitation tells us that the force ... the gravitational force on an object (its weight) at the Earth's surface, using the radius of the Earth as the distance.

In other words, this hypothetical force would fall off slower than the inverse square of the distance. It would thus become more important than gravity when calculating the gravitational pull from ...

Motion - Edexcel The movement of objects can be described using motion graphs and numerical values ... Weight is caused by the gravitational effect of a planet attracting an object’s mass.
