PRAKTIKUM USAHA & ENERGI| Tugas Fisika Kelas X SMKN 1 KATAPANG

Summary

In this practical demonstration, Septian Demi Fuad, a student from SMK Negeri 1 Katapang, explores the concepts of work and energy using common materials. He explains how energy is the capacity to perform work, illustrated through an experiment involving a skateboard, supports made from photo albums, and a toy car. The experiment shows potential energy at its peak when the car is elevated, transitioning to kinetic energy as it descends. The interaction of gravitational forces is highlighted, emphasizing the relationship between potential and kinetic energy, ultimately demonstrating the principles of mechanical energy in a simple and engaging manner.

Q & A

What is the main topic of Septian's presentation?

The main topic of Septian's presentation is the practical demonstration of work and energy using common household materials.

What is the definition of work as mentioned in the script?

Work is defined as the amount of energy required to change the position of an object when a force is applied.

What materials did Septian use for the experiment?

Septian used a skateboard, a photo album as a support, and a toy car for the practical demonstration.

How did Septian set up the experiment?

Septian set up the experiment by placing the support at an angle to create a slope with the skateboard, allowing the toy car to roll down.

What types of energy were discussed in the experiment?

The types of energy discussed include potential energy, kinetic energy, and mechanical energy.

When is potential energy at its maximum in the experiment?

Potential energy is at its maximum when the toy car is at the top position or starting point.

What happens to the potential energy as the toy car moves down the slope?

As the toy car moves down the slope, its potential energy decreases to zero at the bottom position.

What role does kinetic energy play in the movement of the toy car?

Kinetic energy represents the speed of the toy car as it travels from the starting position to the end position.

How is mechanical energy defined in the context of the experiment?

Mechanical energy is defined as the sum of potential energy and kinetic energy, which can be influenced by gravity.

What conclusion does Septian reach regarding gravitational influence?

Septian concludes that mechanical energy can be affected by Earth's gravity, allowing the toy car to move downward.
