Exam #1 Aristotle Onward Quantifying motion Question: acceleration
... Centripetal acceleration is v2/r. This acceleration is due to the gravitational force, so equals g, and is constant for all orbits. The speed v is (circumference / period) = 2r/T Then the centripetal acceleration is proportional to r/T 2 So if the orbital time is shorter, the orbital radius must be ...

... The cannonball moves away from the blue Earth along the curved path shown, losing speed all the while. After reaching a maximum distance (at the bottom of the figure) it starts to fall back, picking up speed. The orbit repeats. This time, it’s a huge ellipse, with the earth at the near (top) focus. ...

What is velocity?
... • What is the difference between speed and velocity? • Speed tells us the distance and time, but not the direction of the object. • When you include the object’s direction, you’re describing the velocity, not speed. ...
