Gravity and the tension in the string.
A pendulum slows down and stops swinging due to air resistance and friction, which act to dampen its motion. As the pendulum swings, it transfers energy into overcoming these forces, resulting in a decrease in amplitude and eventually causing it to come to rest.
An example of a hypothesis for a pendulum experiment could be: "If the length of the pendulum is increased, then the period of its swing will also increase." This hypothesis suggests a cause-and-effect relationship between the length of the pendulum and its swinging motion.
A pendulum's motion is sustained by the force of gravity acting on the mass of the pendulum bob as it swings back and forth. The potential energy of the bob is converted to kinetic energy as it moves, allowing it to continue swinging. Friction and air resistance ultimately cause the pendulum to come to a stop.
Factors that can cause a pendulum to eventually stop swinging include friction at the point of suspension, air resistance, and loss of energy due to damping effects such as sound or heat. Over time, these factors will decrease the amplitude of the pendulum's swing until it comes to a complete stop.

Friction in the air. The pendulum actually swings across small air particles and slows it down. That's why, if you have a bowling ball attached to a string and you hold it up to your face and let go, it will swing back at you - but it is impossible for it to gain enough momentum that you had initially to hit you in the face! Common physics :)
False. Balanced forces do not cause a change in motion. When the forces acting on an object are balanced, the object will remain at rest or continue moving at a constant velocity.
What are the forces that cause a pendulum to swing? How high will a thrown object rise before gravity pulls it back to Earth?
A swinging pendulum follows a simple physical path that is described as simple harmonic motion. A frictionless pendulum would swing forever. Friction generates heat which radiates away energy from the system. Therefore friction will cause the pendulum to slow and stop as all the energy gets removed from the S.H.M. If you rig up a way to replace the lost energy, then the pendulum will continue to swing. This is the method used in a pendulum clock. The energy put into the wind up spring will replace the energy lost due to friction until the spring winds down. The key point is "energy is conserved" which means you cannot create or destroy it. You can only move it from one place to another or convert it into something else.
Keeping the bob of a simple pendulum near the floor reduces the potential energy of the system, which in turn decreases the amplitude of the pendulum's swing. This can help prevent the pendulum from swinging too wildly and potentially causing damage or injury. Additionally, having the bob closer to the floor reduces the distance it needs to fall, which can minimize the impact force when the pendulum reaches its lowest point.
A force that can cause an object to change its speed and direction is known as a centripetal force. This force acts perpendicular to the object's velocity, pulling it towards the center of rotation. Examples include tension in a swinging pendulum or friction on a car going around a curve.
Friction between the pendulum and the air or the supporting point, as well as friction in the pendulum's pivot point, can cause it to slow down and stop. Additionally, if the pendulum loses energy due to collisions or interactions with other objects, it will gradually slow down and eventually come to a stop.
