Consider three properties of the net force on an object: a magnitude, direction, and angle with respect to the objects path. For
the following situation select the choice that indicates wether these quantities are constant or changing during the course of the motion. 1. The magnitude and the angle of the net force with respect to path are constant, but the direction is changing
2. The direction and the angle of the net force with respect to path are constant, but the magnitude is changing.
3. The magnitude and direction of the net force are changing, but the angle of the net force with respect to path is constant.
4. The magnitude, direction, and angle with respect to path for the net force are constant.
5. The magnitude and direction of the net force are constant, but the angle of the net force with respect to path is changing.
To calculate this value we must use the definition of potential energy which tells us that it is the product of mass by the acceleration of gravity by height.
