Method/Pendulum Exercise Worksheet 1. What is the difference between an observation and an inference? Observations are based on collecting knowledge through our senses. An inference is making an educated guess based on observation. 2. In doing science‚ why are hypotheses either supported or not supported‚ but never proved beyond all doubt? There are many other factors that could be unknown and new data could be found in the future to support or not support a hypothesis. 3. For this pendulum exercise

Not only can objects can move in a straight line at a constant speed but they can also change their speed and/ or direction (accelerate or decelerate). Be able to use/produce graphs can help us to describe the movement of an object. These may be distance-time graphs or velocity-time graphs

Everyone has their demons. The Dark Romantic Movement brought that evil into literature in an enticing and spine-chilling way. “The Pit and the Pendulum”‚ by Edgar Allan Poe‚ is emblematic of this movement. Poe used many literary elements and techniques to create a feeling of terror and fear. Three of the strongest elements present are the use of first person narration‚ imagery‚ and symbolism. First person is a powerful choice of narration for this piece. Direct insight into the narrator’s thought

4s and the reaction time while someone is distracting the member is 0.5s‚ and lastly graph matching. 1. Introduction All of us have the ability to move. Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time‚ as we go to work or school‚ participate in sports or even wander around our homes. If we never changed our own motion‚ we would never make it out of bed in the morning. The study

wavelengths) of these radiations can tell us a lot about the molecule‚ atom‚ and nucleus under study. Since diffraction-grating spectrometers and other types of radiation spectrometers are widely used in all sciences you should be familiar with the basic physics of such device What does diffraction look like? When light diffracts off of the edge of an object‚ it creates a pattern of light referred to as a diffraction pattern. If a monochromatic light source‚ such as a laser‚ is used to observe diffraction

Because the work is directly proportional to the displacement given a constant force while power is indirectly proportional to work. Therefore we can conclude that power is also directly proportional
