-- gravity
-- air resistance
The two forces acting on an object that is falling are gravity, which pulls the object downward towards the center of the Earth, and air resistance, which opposes the object's downward motion and slows its fall.
When two or more forces affect an object at the same time it creates a net force.
Gravity is one, and I believe that friction is the other. Friction here being caused by the resistance to motion of the fluid the object is falling in. Generally this is termed air resistance or drag and it is related to the object's velocity and cross section as well as the fluid's viscosity.
falling objects.
The two forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward, while air resistance acts in the opposite direction to slow down the object as it falls through the air.
Gravity and friction.
The two forces that affect acceleration are net force and mass. Acceleration is directly proportional to the net force acting on an object and inversely proportional to the mass of the object.
The two main forces acting on a falling object in Earth's atmosphere are gravity, which pulls the object downward, and air resistance (also known as drag), which opposes the object's motion and slows it down as it falls.
friction and gravity
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.
Gravity: The pull of two objects on each other.Inertia: Basically something that slows any kind of acceleration or deceleration on a moving object.Yup, those two are the main forces that act on a falling object.
When an object is falling at a constant speed, the two forces that must be equal in size but opposite in direction are the gravitational force pulling the object downward and the air resistance force pushing upward. At this point, the forces are balanced, resulting in a constant speed descent known as terminal velocity.
