## Question:

Simple Experiments Give Non-Intuitive, But Not Intuitive Results

Some of the results from simple physics experiments carried out on Earth are not intuitive.

One example is the determination of the acceleration of a ball that has been tossed upwards at zero instantaneous vertical velocity. Another example is the time it takes for two balls to touch the ground after being tossed from the same horizontal surface at different initial horizontal velocity.

Discuss the results and offer the reasoning to explain the seemingly contradictory outcomes.

Introduction

It is essential to conduct experiments in order to study the physics courses on the planet.

They are critical observations of daily phenomena under controlled conditions.

These simple physics experiments don’t have intuitive results (W.T Griffith 8). This paper describes the experimental results for determining the acceleration and time required by two balls with different initial horizontal velocity to touch the ground.

These results may not be intuitive.

The answer to this question can be found in the various perspectives that will be discussed later in this paper.

The results of experiments in physics should not be intuitive because they are trying to prove theories.

Throwing a ball up

It is common to see objects being thrown upwards fall to the earth.

What miracle is this?

Why don’t they just climb to infinity?

Analysing the experiment’s results reveals how the ball velocity changes over time and how high the ball can travel, explaining why the results are not intuitive (Conrad, 2015).

This experiment should be carefully considered when dealing in the direction of acceleration or velocity vectors.

In this experiment, you can determine exactly the velocity change.

Let’s assume that the ball was tossed upward at 20 m/s.

For convenience calculations, let’s assume that gravity is the main force that causes this ball to accelerate downwards at around 9.8m/s.

Gravity acceleration occurs in the opposite direction to the initial speed of the ball. Therefore, the velocity drops by 10 m/s each second.

It is therefore easy to calculate the instantaneous speed of the ball. For example, the velocity of our ball here is 10 m/s.

It is possible to determine the height that the ball can reach by measuring the moment when its velocity becomes zero.

Falling Objects and Projectile Motion

Two identical balls of the same horizontal velocity are thrown off the same plane surface in this experiment.

This experiment will show you which ball will impact the ground first.

The results of this experiment can be used as a guide to determine how long each ball takes for it to hit the ground. Also, the distance the ball falls at different times. This proves that this experiment has proven to be a good example of ground principles of operation (Peter, Sally, 2016,).

It was found that the ball with a higher velocity initially travels faster and covers more distances within a given time.

Due to gravity acceleration, the ball’s velocity increases over time.

These results are, in conclusion, contradictory.

Because air resistance is too small to have a significant effect on the experiment, it has been left out of this analysis (W.T Griffith 8).

It is possible to see the effect clearly when objects with small weight and large surfaces like a piece paper are used.

You can get velocity and distance using the following formulae

V=V0+ at

Distance = V0 + 1/2at2.
