... In free fall, the force of gravity is an unbalanced force that causes an object to accelerate. Near Earth’s surface, acceleration due to gravity is 9.8 m/s 2. Objects falling through air experience a type of fluid friction called air resistance. Air resistance is not the same for all objects. The gr ...

... The radian is used when measuring a new quantity known as angular displacement, θ, measured in radians (rad). One radian represents an arc with a length of one radius of that circle. This is the displacement (in angle form) around the arc of a circle, which has an equivalent angle in degrees. There ...
