i dont know im not a smart ass you know!!!!
Gravity and friction.
friction and gravity
Gravity and friction there are others also like magnetism for example..
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
Friction and gravity affect your score, but not your skill.'Skill' is your ability to account for the effects of friction and gravity,while you plan the eventual outcome that you want to achieve.
Friction can affect an object's speed by reducing it over time, as it acts in the opposite direction to the object's motion. However, friction does not directly affect an object's velocity which is a vector quantity that includes both speed and direction.
Speed, shape and frontal cross-section. Viscosity, texture, friction, gravity, velocity, size, and shape can all affect air resistance.
Two forces that can affect an object's velocity are acceleration and friction. Acceleration can increase or decrease the velocity of an object, while friction can slow down the object's motion by opposing its direction of movement.
Friction and acceleration due to gravity do not directly affect the weight of an object. Weight is determined by the gravitational force acting on the object, which is independent of these factors. However, friction can affect the apparent weight of an object on a surface by opposing the force of gravity.
Speed, shape and frontal cross-section. Viscosity, texture, friction, gravity, velocity, size, and shape can all affect air resistance.
Factors that can affect the value of the horizontal velocity of a ball include the initial speed at which the ball was thrown or kicked, the angle at which it was launched, air resistance, and any external forces acting on the ball such as friction or gravity.
Any acceleration.Acceleration in physics is classed as loss or gain or speed, or any change in direction.
