Sally and Sam are in a spaceship that comes to within 18,000 km of the asteroid Ceres. Determine the force Sally experiences, in N, due to the presence of the asteroid. The mass of the asteroid is 8.7 1020 kg and the mass of Sally is 80 kg. For calculation purposes, assume the two objects to be point masses.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Use the drop-down menus to complete each sentence. the mass of the cylinder is manipulated. this is the variable. the temperature of the water changes as the mass of the cylinder changes. temperature of the water is therefore the variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the system that is held constant is the .

What is a good example of instantaneous speed
