|
|
mass
|
|
|
acceleration
|
|
|
distance

|
|
time

Explanation:
Detailed explanation-1: -This shows that the elements involved in falling can affect it in different ways. The first of these elements is air resistance. Other elements include velocity, the shape and surface area of the object, drag force, and the angle at which the object is thrown.
Detailed explanation-2: -The force of gravity, g = 9.8 m/s2 Time to splat: sqrt ( 2 * height / 9.8 ) Velocity at splat time: sqrt( 2 * g * height ) Energy at splat time: 1/2 * mass * velocity2 = mass * g * height.
