Air resistance causes deceleration by blank blank and free fall has blank that is caused by gravity
Air resistance causes deceleration by drag force and free fall has acceleration that is caused by gravity.
Air resistance causes deceleration by opposing the motion of an object and exerting a force in the opposite direction. Free fall has acceleration that is caused by gravity.
Air resistance causes deceleration by opposing the motion of an object moving through the air. The speed at which an object decelerates due to air resistance depends on factors such as the object's shape, surface area, and velocity. To calculate the deceleration caused by air resistance, you need to consider the drag coefficient, cross-sectional area, and the object's velocity. These factors can be used in equations such as the drag equation or the equations of motion to determine the deceleration.
On the other hand, free fall refers to the motion of an object falling under the sole influence of gravity, without any other forces acting on it. When an object is in free fall, it experiences an acceleration due to gravity, which is approximately 9.8 meters per second squared (abbreviated as 9.8 m/s^2) on the surface of the Earth. This acceleration is always directed downward towards the center of the Earth. The force of gravity causes objects in free fall to accelerate, which means their velocity increases over time. However, if there are no other forces at play, such as air resistance or propulsion, the object will continue to accelerate until it reaches its terminal velocity, which is the maximum velocity it can attain in free fall due to air resistance balancing out the force of gravity.
