The ball of mass 1000g is dropped from a height of 25m. Calculate,

1. The potential energy
2. Velocity

1. P.E. = mass * g * height = 1 kg * 9.8 m/s^2 * 25 m

2. P.E. top = K.E bottom

m g h = 1/2 m v ^2 ... v = √(2 g h)

Did you know that potential energy and velocity are closely related when it comes to objects in motion? In the scenario where a ball with a mass of 1000g is dropped from a height of 25m, we can calculate both its potential energy and velocity. 1. Potential energy refers to the energy possessed by an object due to its position or state. In this case, the potential energy of the ball can be calculated using the formula: potential energy = mass × gravity × height. Plugging in the values, we get potential energy = 1000g × 9.8m/s² × 25m. 2. Velocity, on the other hand, represents the speed and direction of an object's motion. When the ball is dropped, it will accelerate due to the force of gravity, which causes an increase in its velocity over time. While the velocity calculation involves various factors, in this case, we can use a simplified formula to find the final velocity when an object is solely influenced by gravity: final velocity = √(2 × gravity × height). Substituting the values, we have final velocity = √(2 × 9.8m/s² × 25m). By understanding these calculations, we can gain insight into the relationship between potential energy and velocity, and how they play a role in the motion of objects.
