Which of the following best describes weight? The amount of space an object takes up
The amount of matter in an object
The force on an object due to its mass and gravity
The force on an object due to its speed and locatio

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

How are calculation for velocity and speed different

What is a good example of instantaneous speed
