Yes, many physical phenomena can be accurately described and predicted using Newtonian physics, particularly for objects with speeds much slower than the speed of light and on scales larger than atoms. However, when dealing with very small scales (like quantum mechanics) or very high speeds (like near the speed of light), Newtonian physics may not provide accurate predictions.

What are the two major divisions of physics?
The two major divisions of physics are classical physics and modern physics. Classical physics deals with the study of macroscopic phenomena using principles such as Newtonian mechanics and thermodynamics. Modern physics, on the other hand, explores the behavior of matter and energy at the atomic and subatomic levels, incorporating theories like quantum mechanics and relativity.
What are the key differences between Newtonian physics and Einsteinian physics?
Newtonian physics, developed by Sir Isaac Newton, describes the motion of objects in the everyday world using concepts like force, mass, and acceleration. It is based on absolute space and time. Einsteinian physics, or the theory of relativity, developed by Albert Einstein, revolutionized our understanding of space and time. It describes how gravity affects the fabric of spacetime and how objects move in relation to each other. It is based on the idea that space and time are relative and interconnected. The key differences between the two are in their treatment of space, time, and gravity. Newtonian physics is a simpler, more intuitive description of motion, while Einsteinian physics provides a more accurate and comprehensive understanding of the universe.
How can one determine the time interval in physics?
In physics, the time interval can be determined by measuring the difference between the initial and final times of an event or process. This can be done using a stopwatch, clock, or other timing devices to accurately record the start and end times. The time interval is then calculated by subtracting the initial time from the final time.
What do scientist using classical Newtonian expect to observe during a photoelectric effect?
Scientists using classical Newtonian physics would expect to observe a gradual increase in the kinetic energy of emitted electrons when exposed to increasing light intensity in the photoelectric effect. They would also expect the emission of electrons to start immediately upon exposure to light, regardless of its frequency.
What measurements is best understood using einsteins concepts rather than newtonian physics?
Measurements involving high speeds, strong gravitational fields, and extremely small scales are best understood using Einstein's concepts of special and general relativity rather than Newtonian physics. Examples include the behavior of particles near the speed of light, the bending of light by massive objects, and the structure of the universe on a cosmic scale.
When does newtonian physics fail to explain motion correctly?
Newtonian physics fails to explain motion correctly in extreme conditions such as at speeds approaching the speed of light or in the presence of very strong gravitational fields where the effects of relativity become significant. Additionally, at the quantum level, where particles behave in ways that cannot be predicted using classical physics, Newtonian physics also breaks down.

What is the physics behind a truss bridge?
A truss bridge uses trusses as the load bearing element of the bridge. Using statics physics, a truss bridge applies Newtonian motion to ensure that the load bearing elements do not go out of a tension/compression equilibrium.
How can the pH of rainwater be determined accurately?
The pH of rainwater can be accurately determined by collecting a sample of rainwater and using a pH testing kit or pH meter. The kit or meter will provide a numerical value that indicates the acidity or alkalinity of the rainwater.

How could the age of the skull could be determined most accurately by using?
The age of a skull can be most accurately determined using radiocarbon dating or by analyzing the teeth for developmental changes like eruption and wear patterns. Additionally, studying the growth plates in long bones can also provide valuable information about the individual's age at death.
How can one determine relative humidity accurately?
Relative humidity can be accurately determined using a hygrometer, which measures the amount of water vapor in the air compared to the maximum amount the air can hold at a given temperature.
How do know how fast light travels?
Its speed has been measured accurately, using lasers.
How can one determine the power in physics?
Power in physics can be determined by calculating the amount of work done per unit of time. It is measured in watts (W) and can be calculated using the formula: Power Work / Time.
