Which of the following never occurs during the orbit of a planet. Question 5 options: Acceleration is perpendicular to velocity Acceleration is angled opposite to velocity Acceleration is angled in the same direction as velocity Acceleration is in the same direction as velocity

Homework Answers

Answer #1

If a planet moves in an orbit around a star under the central force, then, the acceleration is always towards the center,
   
And the velocity is
   
Now in an orbit is never zero. So, in an orbital motion, velocity and acceleration can't be in the same direction.
There is always a component of the velocity in the direction thatis not there in the case for the acceleration.
  So, the last option is correct.

Which of the following statements about projectile motion ARE correct? Group of answer choices The velocity direction is changing across the motion trajectory, but the acceleration direction remains the same. The direction of both velocity and acceleration are changing across the motion trajectory For a free fall object(the horizontal component of the initial velocity is zero), its velocity is zero when it reaches maximum height, but its acceleration is not zero at the same time. For a free fall object(the...
