1. The ball swings downward like a pendulum. As it starts swinging, the energy changes from potential energy to kinetic, or moving, energy. The total amount of energy, moving plus stored, stays the same; it only changes form.
2. The Earth's gravity keeps the Moon orbiting us, because It keeps changing the direction of the Moon's velocity. This means gravity makes the Moon accelerate all the time, even though its speed remains constant.
3. f the rope is cut, the tension force in the rope no longer acts on the ball; the ball is subjected to a single force, the gravitational attraction of the earth. Since there is no initial air resistance, the ball begins to free fall and accelerate. The drag increases until it is equal to the weight.
Hope makatulong sayo. Paki brainlestttt na lang:>
