Final answer:
According to Newton's second law of motion, the force needed to slide an object across a surface is directly proportional to its mass and acceleration.
Step-by-step explanation:
The relationship between the mass of an object and the force needed to slide it across the surface is described by Newton's second law of motion. According to this law, the force required to move an object is directly proportional to its mass and acceleration. This relationship can be expressed by the equation F = m*a, where F is the force, m is the mass, and a is the acceleration.
For example, if you have two objects with different masses, the object with a greater mass will require a greater force to move it across the surface compared to the object with a lower mass. This is because the force needed to overcome the inertia of an object increases with its mass.
Additionally, the coefficient of friction between the object and the surface also affects the force needed to slide the object. Higher friction between the object and the surface would require a larger force to overcome the friction and initiate motion.
