How Do You Know If Velocity Is Changing? |

Because velocity is the rate of motion of an object in a specific direction, either an increase or decrease in the object's speed or a change in its direction of travel causes its velocity to change. This change in velocity is defined as an acceleration, which according to Newton's laws of motion occurs because of an unbalanced force acting on ...

4 days ago· If it does nothing else, it will return to that same perigee point after one complete orbit. On the other hand, when it gets to the apogee point, it can fire its engine again to speed up again. This will raise the perigee point; the right change in speed at apogee will raise the perigee to make the orbit circular again, at the new altitude.

How Does Weight Affect Speed? What's ...

Acceleration causes an object to change its speed or its direction of motion. Newton's second law states that a force is a product of an object's mass multiplied by an object's acceleration. Weight itself is a type of force in which the acceleration on the object is due to the effect of Earth's gravity.
