force
... This object is moving in a circular path at a constant speed. The string is constantly exerting a force on the object At any point in time, there is a net force on the object (no opposite forces) According to Newton’s First Law, the object must be accelerating. How? It is moving at a constant speed. ...

1.1 - Newtonian Gravitation and Orbits - K
... In grade 11 Physics, we said that g was equal to 9.81m/s2. In truth, this is just an approximation, and the value of g varies at different points on the earth depending on how far one is from the earth’s surface. This is because of the inverse-square relationship of the Universal Gravitational Law ...

... 1) Mass is often defined in elementary school as “the amount of space an object takes up”. Why is this not correct? 2) Would your mass be different if you were on the moon right now? 3) What would a 75 kg person weigh on Earth? What would this person weigh on Mars where the acceleration due to gravi ...
