Mass (gravity) & friction!
The friction between the two surfaces opposes the sliding motion by creating a resistance force. Factors such as surface roughness, materials, and applied force affect the amount of friction generated.
Rolling motion is easier than sliding motion because rolling motion has a lower friction force exerted upon the object than sliding motion.
The motion of a boy sliding down a slope is known as translational motion. This is because the boy is moving in a straight line along the slope without any rotation or spinning. The motion is influenced by factors such as gravity, friction, and the angle of the slope.

Friction is the force that opposes the sliding motion of two surfaces in contact with each other. It acts in the direction opposite to the motion and can be influenced by factors like the type of surfaces, their roughness, and the force pressing them together.
Friction between two objects sliding past each other opposes the motion and generates heat. It reduces the speed at which they slide and can affect their ability to come to a stop or maintain a constant velocity. The amount of friction depends on the surfaces in contact and the force pushing them together.
The two factors that affect orbital motion are the mass of the objects involved and the distance between them. Gravitational force is stronger with larger masses and decreases as distance between objects increases.
Sliding friction, or more formally known as Dynamic Friction, or Kinetic Friction, is a resistive force that arises when one object is in contact with another object and the objects are in motion with respect to each other. Friction is called a resistive force because it always resists, or pushes against, the initial force causing the motion..The factors that affect the magnitude of dynamic friction are:the coefficient of dynamic friction between the two bodies; andthe magnitude of the original force responsible for the motion.
For a pendulum, factors such as the length of the string, the mass of the bob, and the angle of release can affect the simple harmonic motion. In a mass-spring system, the factors include the stiffness of the spring, the mass of the object attached to the spring, and the amplitude of the oscillations. In both systems, damping (air resistance or friction) can also affect the motion.
Sliding along a horizontal table does not involve projectile motion. Projectile motion refers to the motion of an object that is thrown or projected into the air and moves under the influence of gravity. In the case of sliding on a table, the motion is typically influenced by friction rather than gravity.
Factors that may affect the motion of objects include the object's mass, the force acting upon it, friction with the surrounding surfaces, and external influences such as air resistance or buoyancy. Additionally, the shape and surface area of the object can also impact its motion.
Static friction can affect circular motion by providing the necessary force to keep an object moving in a circular path without slipping. It acts in the direction opposite to the motion of the object, preventing it from sliding out of the circular path. This frictional force helps maintain the object's velocity and direction in the circular motion.
