Pendulum and spring
In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations.
Any system that exhibits back and…
Could You…? Math Inquiry
Could you run 0.8 kilometres in one minute?
The fastest 100m sprint speed record is held by Usain Bolt , reaching the speed of 43.94 kph. 0.8 km is 800 meters. For you to run 800 meters in 1 minute you would need to reach the speed of Usain bolt speed: 43.94 x 800m= 35152 m/s. Though human endurance comes into play as well, as a person cannot run their top speed for more than 8 seconds. Usain Bolt was able to keep 95% of his top speed for 8 seconds during his…
This practical was an investigation involving the use of a tennis ball and a meter ruler. The tennis ball was held and dropped at a specific height above the ground. The height of the bounce was then measured. This investigation was carried out to find out whether the efficiency of the bounce varied with the height of release of the tennis ball. If the bounce were 100% efficient, then the tennis ball would have bounce off the ground and return to the starting height.
The Accomplishments of Jean Jacques Rousseau
Jean Jacques Rousseau was one of the few people who could be considered as a jack of all trades. He was a philosopher, author, and composer, and he also dabbled in botany and mathematics. He produced many wonderful works in his lifetime and had made several important contributions to music, literature, and political philosophy.
His professional success belied the difficult childhood that he had. His mother died a few days after he was born, and his…
Paper Bullets Experiment: Data Analysis
The scientific question that was investigated by the paper bullets experiment asked, “Does the width of a paper bullet affect the distance it travels when it is launched?” The hypothesis that goes along with that question is, “If a paper bullet has a larger width, then it will travel a shorter distance than a standard paper bullet with a width of 4cm.” Variables in this experiment included independent variable (width of the starting piece of paper used to…
The scientist, Sir Isaac Newton, helped to organize the thinking about forces by formulating three laws. In his book Newton describes his three laws of motion. Newton’s Laws are all around us. To prove this, you will conduct 14 different activities showing everyday examples of these laws.
You will start at a lab station and then move from station to station until you have completed all 14 activities.
You will have 3minutes to do the activity at each lab station.
At the end of this topic, you will be able to understand about:
Brakes are classified into six types based on the nature of power employed. Brakes are employed to stop the vehicle in the least possible distance.
The following media (Brakes) explains about the functions and types of brakes.
In this media, you will learn about ‘Brakes’.
Brake is one of the vital control parts of a vehicle.
Brakes are needed to stop the vehicle in…
Sir Isaac Newton, does the name sound familiar? That’s because he discovered gravity by an apple falling on his head from a tree. He didn’t discover the law of gravity right then and there, but it was this experience that helped set the course for the rest of his life. Sir Isaac Newton’s life was a combination of childhood tragedies, educational struggles, and many achievements. So let’s go back to where it all started when he was born.
Sir Isaac Newton was born on December 25, 1642 (January 4th…
Physics is everywhere. Especially in NASCAR which stands for National Association for Stock Car Auto Racing is a racing sport which the racing cars have motion. “NASCAR is motorsport's preeminent stock-car racing organization. The three largest racing-series sanctioned by this company are the Sprint Cup Series, the Xfinity Series, and the Camping World Truck Series.”(Mukul Bhatia.What is NASCAR?.www.quora.com.) On the rough racetrack nascar cars are made to be driven in extreme conditions. In…
Changes affect people every day, and people react to changes in many ways. In Long Day’s Journey into Night, the characters experience many trials and obstacles in their lives that induced a change. In physics, there is the principle known as the Coriolis Effect or Force, which is the effect a rotating object has on the motion of another object. The trials experienced in the lives of the characters are the Coriolis Force in their lives that induced the change in their behavior or lifestyle.
