Thus, a planet will experience less force when furthest from the sun. You might really need to view the informative graphic . Short Answer 11. Explain how something can be traveling the same speed yet be accelerating at the same time. The object would have to be traveling in a curved path since it is accelerating.
Acceleration is defined as a change in velocity over a change in time.
If the speed is staying the same, then the velocity must be changing by altering the direction in which the object is heading. A force is required to do this. See an informative animation and further explanation. Both are being pulled by the earth due to the gravitational force. The moon stays in orbit due to it having the appropriate tangential velocity that keeps it from coming closer to the earth's surface.
