What is the relationship between gravitational attraction and mass and distance?

• If mass increases, the force of gravity increases.

  If distance increases, then gravity decreases.

• If mass increases, then gravity decreases.

  If distance increases, then gravity increases.

• there is no relationship

What is speed?

• when two objects collide

• any movement that is a push or a pull

• the distance an object moves divided by the time it takes to move that distance
